The Heating Rate Controller provides two independent temperature-control channels for externally powered DC heaters. Learn what each channel does, how it connects, and how to operate it under the site's approved procedure.
Each channel has an Omron temperature controller, a maintained CONTROL selector, a momentary HEATER ENABLE button and a HEAT ACTIVE indicator. The temperature controller monitors a Type K thermocouple and commands the heater through the control circuit.
The red-and-black connectors are arranged in two pairs per channel. Connect the external DC supply to the upper pair marked PSU IN. Connect the heater to the bottom pair marked HEATER OUT. Use the matching green Type K connector for temperature feedback.
Specified design limits: 0–60 V DC and 15 A per heater channel. External power supplies, wiring, connectors and protection must be suitable for the intended duty and verified before use.
Neither channel’s Murata DC voltmeter has the manufacturer-specified external input-wire fusing fitted. The meter’s internal resettable fuse does not replace this protection. Do not authorise live heating until the meter input wiring and its protection have been corrected, inspected and recorded alongside the other equipment safety checks.

The front-panel connector references and the electrical drawings use different naming systems for the same four red/black pairs:
| Channel | Front-panel reference | R1.2 drawing reference | Connection |
|---|---|---|---|
| 1 | JP1 | JP1-IN | Upper pair — external PSU IN |
| 1 | JP2 | JP1-OUT | Lower pair — HEATER OUT |
| 2 | JP3 | JP2-IN | Upper pair — external PSU IN |
| 2 | JP4 | JP2-OUT | Lower pair — HEATER OUT |
Use the permanently fitted equipment markings and confirm the actual channel and polarity before making connections. The drawing reference is not a substitute for identifying the physical connector.
The amber HEAT ACTIVE lamp shows enabled heating demand, not measured heater current. See the electrical reference for circuit details.
The equipment has one controlled operating procedure. Use the complete SOP for experiment setup, controller programming, energizing the external supply, heating, shutdown and abnormal conditions.
The full SOP contains the required sequence, expected controls and indicators, and action to take if a check fails. Use its printable version at the test station.
The Omron programme, heater ENABLE circuit and external DC power supply are separate. Read each indication below before starting or diagnosing a test.
| Display or control | Meaning | Important distinction |
|---|---|---|
| Omron PV / SP | PV is the thermocouple temperature; SP is the current target temperature. | Neither shows measured heater current. |
| Omron r-r = rst | The Omron programme is in RESET. | RESET is not electrical isolation. Verify that output demand is OFF in the approved configuration. |
| Omron r-r = run | The Omron programme is executing. | The heater still needs ENABLE, external PSU output and actual heat demand before it can deliver power. |
| EAO ENABLE ring | ON: the Finder 13.61 heater-enable output is asserted. OFF: heater ENABLE is not asserted. | Does not start or stop the Omron programme; does not prove the external DC supply is isolated. |
| Amber ACTIVE LED | ON / pulsing: ENABLE is ON and the Omron is requesting heater drive through the Weidmüller interface. | Does not prove actual current or heating. The indicator can pulse during proportional control. |
| Murata DC VOLTS | Shows the matching external PSU input voltage when the input exceeds approximately 6 V. | Does not measure heater output or current. A blank display does not prove safe isolation. External input-wire fusing is currently not fitted; see the safety notice. |
With the specified wiring, the ACTIVE LED positive is connected to Finder 13.61 terminal 14 (EN1/EN2); the negative is switched by the relevant Weidmüller demand interface.
| EAO heater ENABLE | Omron heating demand | Amber ACTIVE |
|---|---|---|
| OFF | OFF | OFF |
| OFF | ON | OFF |
| ON | OFF | OFF |
| ON | ON | ON / pulsing |
This table describes the control-command indication, not whether the external PSU is switched on or whether the heater is actually carrying current.
Abort the test after any supply interruption. Keep the external DC heater supply isolated until the ENABLE state, Omron RESET behaviour and safe restart conditions have been checked. If an indicator behaves differently from the table, stop and investigate using the approved fault procedure.
Set up the controller, create and select programmes, and find the correct menu on the front panel. The worked examples are learning aids; verify settings against the fitted Omron model and the intended test.
Build a ramp, soak and step programme (up to 32 segments; memories 0–7), select any documented Omron sensor/input for OFFLINE planning, preview the commanded setpoint and inspect non-blocking sensor compatibility warnings and practise the real five-button sequence. The offline simulator retains practice programmes in the browser, separates d.prg (editing) from prg (run selection) and provides a virtual power cycle. It is for keypad practice, not simulation of real heater outputs or safety devices.
Choose the target temperature, ramp rate, hold time and memory slot, then follow the exact Omron display and button sequence one step at a time. No cable or account required.
Move through setting levels with illustrated LEVEL/MODE routes. Search every documented mnemonic, inspect parameter explanations, follow each MODE step, and view conditional hardware settings without hiding the full reference. Select the model suffix printed on the physical controller; omitted parameters depend on firmware, protection and active settings.
These instructions cover Omron E5CC-T series controllers. Check the complete nameplate and option suffix on each controller before changing hardware-dependent settings; USB identification returns only a model prefix. The step-by-step guide includes the creation, retention check and selection of example Programme 1 (50 °C at 2 °C/min and 15-minute soak), exact LEVEL/MODE steps, which settings are global, programme-wide and segment-specific, Operation Level monitors, and how to find and inspect the assigned PID parameters.
Start with the 50 °C worked example, then use the fixed 80 °C example, 120 °C ramp example and ramp calculator as further exercises. The prg selection must be checked separately from d.prg before RUN.
Use this section when setting up a channel or checking its performance. Use the exact model suffix and firmware shown on the installed controller when choosing parameters. Hardware options and available settings vary by model.
in-t matches the actual physical sensor, its permitted range/resolution, the units and the global upper/lower SP limits. The Windows app can plan other documented sensors, but cannot identify the external probe by USB.d.prg and segment fields. Then, in Operation Level RESET, select the intended RUN programme using prg and verify pgsg.For full button-by-button instructions, open the linked E5CC-T programming guide. Verify the settings on each physical controller during commissioning.
Autotune is not a substitute for verifying safety limits. It is unsuitable during an actual thermal-runaway event.
Use the instructions matching the controller's exact part number and firmware. Match parameters to the fitted controller, sensor and intended heating test.
Use the Windows application to prepare a local programme, read a single Omron E5CC-T controller using E58-CIFQ2, review applicable settings and carry out deliberate, verified transfers. The application does not monitor live heater current, provide electrical isolation or replace commissioning checks.
Create or edit any of eight local programme drafts, each with up to 32 ramp/soak/step segments. The profile can be graphed and exported even when its target exceeds the chosen controller sensor range; the app gives an explicit warning instead of discarding the entered temperature.
Choose among 30 documented input codes (0–29): Pt100, JPt100, supported thermocouple/IR types and analogue current/voltage. The last group needs configured signal scaling (C3:0001–0003); do not label it in °C unless that is the actual engineering unit.
USB 0503 returns only a 10-character prefix, for example E5CC-TQX3A. It does not identify 5M or the final -NNN option code. Check the printed nameplate and choose its exact full model in the Windows dropdown.
The app uses the documented model option matrix to show only plausible event input, CT, RS-485, transfer-output and other option settings. An option still needs a successful actual register read and a qualified write procedure; selecting it is not proof of physical fitment or wiring.
Read the USB model prefix and controller status; confirm the nameplate suffix for this connection. Start in read-only mode; enable writes only during an authorised isolated setup procedure.
Capture all eight DA programme memories (150 registers each) and supported C0/C1/C3/C5 settings. Failed or unavailable hardware options are not interpreted as zero. Retain the backup and recorded controller identity.
View the commanded SP curve, edit freely and compare all targets against the actual verified input range, decimal resolution and sl-h/sl-l limits. A conflict produces a warning and an offer to propose a compatible global sensor range, never an automatic rewrite.
Optional hardware parameters follow the confirmed full model and successful readback. Programmes, sensor choices, PID parameters, output assignments and safety settings are not all interchangeable write operations; unsupported or hazardous changes are kept read-only.
For a proposed C3 input change, preview the exact selected registers, isolate heater supplies, apply/read back in setting area 1, use Finish + Return to normal, visually verify normal PV/SP, then reconnect and perform a fresh Step 2 read/backup. Only then preview, write RAM, verify, save and finish the selected DA programme. Do not confuse CMW OFF with leaving setting area 1 or with heater disable.
The portable Windows package has separate read-only and isolated-setup launchers. Selecting a launcher does not itself authorise controller writes or heater operation.
Look up an electrical designation, manufacturer part number or replacement item in the single searchable component register.
Includes controllers, relays, SSRs, protection, switches, indicators, terminals, connectors and manufacturer documentation.
Open component register →Manufacturer documents are linked directly from the component register. Omron programming has a separate operating guide.
Safe operation depends on verified controls, heater connections, independent external supply isolation and protection for each installation and test.
Isolate and prove dead on both the mains inlet and the separate 0–60 V DC heater supplies. Maintain cabinet and door protective-earth bonding, verify the specified component ratings, and ensure the heater-off state and power restoration are tested. The Murata input-fusing discrepancy must also be resolved and recorded before live operation.
Use the for routine tests and the Omron guidance for programming. ACTIVE indicates a switching command, not confirmed heater current.
