E5CC-TQX3A5M-000 — front-panel simulator validation

Test type: Read-only menu inspection (not heating programme execution)
Reference: Omron H185, E5_C-T User’s Manual, §§ 3-3, 3-4, 4-1 and 4-7
Simulator: https://techtinker.club/heater/program-tools/#simulator
Target model: E5CC-TQX3A5M-000 on both channels
Issue: E58-CIFQ2 detected in Device Manager but COM-port driver unavailable (Code 28). This test does not require a COM port.

Safety boundary: Use USB setup power only, normal controller supply safely isolated, and external heater supply safely isolated. No RUN command; no MODE+DOWN RUN/RESET combination; no changes to stored parameter values or initial configuration. The only adjustable value in this test is the navigation selector d.seg (0, 1, end). Don’t change d.prg if you are uncertain what it selects. If a menu behaves unexpectedly, record it and stop rather than guessing.

S.ERR usually means a sensor input error (e.g. missing or unsuitable thermocouple). This is a separate issue from the absent Windows driver. Do not attempt to suppress it by altering in-t during the menu test.

Record these details

  • Date/time: __________
  • Physical channel: ☐ CH1 ☐ CH2
  • Full nameplate suffix (photo): __________
  • Initial upper display: ____ Lower display: ____
  • S.ERR flashing? ☐ Yes ☐ No
  • Normal mains and heater DC safely isolated? ☐ Verified
  • Controller powered by E58-CIFQ2 only? ☐ Yes
  • Menu protection message or locked key? __________

A. Basic navigation (3 minutes)

Start at normal PV/SV screen.

Check Key press Expected screen Observed screen / value
A1 Brief LEVEL once (left rectangular key) d.prg _______
A2 Brief MODE once (second looping-arrow key) s-no _______
A3 Brief MODE once d.seg with end normally _______

Do not change s-no or d.prg. Their displayed values may differ from our simulator’s default. Record them exactly.

B. Segment 0 (5 minutes)

At d.seg, select 0 using UP or DOWN. Selection is navigational; it is not the segment’s end setting. Press MODE to see the first parameter. Keep pressing MODE just long enough to record the relevant screen codes and values.

Check Omron display Meaning Actual value / visible?
B1 d.seg = 0 Selected segment _______
B2 styp Ramp / soak / step if rate-of-rise mode _______
B3 sp Target setpoint _______
B4 pr Rate slope if ramp _______
B5 time Time if applicable _______
B6 Next parameter after last segment item Menu transitions _______

Write N/A, not a guessed value, if a parameter does not appear.

C. Segment 1 (5 minutes)

Return to d.seg using MODE (brief = next; held ≥1 s = previous where supported). Select 1; press MODE and record all segment items. Do not edit them.

Check Omron display Actual value / visible?
C1 d.seg = 1 _______
C2 styp _______
C3 sp _______
C4 pr _______
C5 time _______
C6 How to return to d.seg _______

D. Initial settings — inspect, don’t edit (7 minutes)

From Programme Setting Level return to Operation by pressing LEVEL briefly three times. From Operation hold LEVEL for at least 3 seconds to display in-t. Use MODE to move through parameters, without UP or DOWN.

Screen Meaning Actual value Shown / hidden
in-t Sensor type ____ ____
d-u °C / °F ____ ____
cntl PID / ON-OFF ____ ____
t-u Programme time unit ____ ____
t-pr Programming method (critical): time or pr ____ ____
pru Rate denominator (minute/hour) ____ ____
rtsm RESET behaviour ____ ____
p-on Power-restoration behaviour ____ ____
eset Programme-end behaviour ____ ____

Important: The simulator assumes t-pr=pr, t-u=h-m and pru=m. If the real controller is in time mode, the actual segment menus differ from the simulator’s rate-mode menus. Record the mismatch; don’t change t-pr to make this test pass.

Exit the Initial Setting Level with LEVEL held at least 1 second.

E. Safe navigation checks (2 minutes, optional)

  • From a parameter page, hold MODE ≥1 s: did the display return to the previous parameter? ____
  • Brief LEVEL presses correctly cycle Operation → Program → Adjustment → PID → Operation? ____
  • d.seg=end behaves as programme-wide settings, not an END segment? ____

Do not test RUN/RESET, output controls, editable digit shifting or protected/advanced settings during this session. PF can be user-configured to another function, so leave it alone for now.

Physical controller observation — 13 October 2026 (Channel not yet identified)

Reported by user while controller is powered from E58-CIFQ2 with Windows driver unavailable (Code 28). Normal sensor input currently reports flashing S.ERR.

  • Before change: t-pr=time; when d.seg=0, the actual controller displayed only sp and time. This is consistent with step-time programming and does not prove the simulator’s rate-of-rise display is wrong.
  • User-initiated change: t-pr was changed to pr. Subsequent Segment 0 parameter visibility has not yet been checked.
  • Observed configuration: pru=m, t-u=h-m, rtsm=stop, eset=rst. Originally p-on=cont; user subsequently changed p-on=rst. Confirmed retained after full USB unplug/reconnect power cycle on 13 October 2026; actual RUN-to-power-loss recovery and physical output behaviour remain untested.
  • Programme-wide end settings: With d.seg=end, physical controller showed rpt=0 (no repeat) and link=end (no chaining). Together with eset=rst, the configured programme is intended to enter RESET after finishing, subject to bench verification.
  • Programme slot: d.prg=0 physically observed; all segment and end-menu values above relate to currently selected programme 0.

  • After switching to t-pr=pr: The user confirmed s-no=1 (one active segment: segment 0). Setting d.seg=0 revealed styp=ramp → sp=50 → pr=0 in that order. Validates the rate-mode display flow. Omron H185 §4-7-4 explicitly says pr=0 causes the segment to behave as a step despite styp=ramp; a positive rate must be set for an actual ramp. Do not run the test profile yet.

  • Safety follow-up required: Omron H185 §4-7-4 explains that p-on=cont restores interrupted controller programme status. For the heater cabinet, recommend assessment of p-on=rst to inhibit automatic post-power-loss continuation. This concerns loss of Omron controller supply, not ordinary PWM/SSR switching of the independent heater DC supply. rtsm=stop alone is not physical isolation; Omron H185 §6-5 confirms mv-r (MV at Reset) is an Adjustment Level parameter masked by default, with factory default 0.0% for standard control. Its actual value is not yet verified on this unit. Do not change parameter masking merely to display it; verify later by a qualified commissioning method alongside the hardware fail-safe.
  • Next validation: On programme 0 with t-pr=pr, select d.seg=0, leave values untouched, and record the next display reached by pressing MODE immediately after pr=0, to check simulator navigation/wrap-around. Then, if desired, inspect d.seg=end programme-wide parameters again. No RUN or output testing on USB setup power.
  • Limitations: USB-only inspection provides no heater-output or restart-interlock qualification.

Results

  • Actual t-pr: ____ ; actual t-u: ____ ; actual pru: ____
  • Does styp appear for segment 0? ☐ Yes ☐ No
  • Does pr appear when the selected segment is a ramp? ☐ Yes ☐ No
  • Does time appear for a soak? ☐ Yes ☐ No
  • Did short LEVEL/MODE navigation differ from simulator? __________
  • Any unexpected screens or messages: __________
  • Photos recommended: A1–A3, B1–B4, C1–C4, D’s t-pr and rtsm.

Interpretation and next actions

  • Differences in parameter visibility may be caused by the t-pr programming method, active parameter masking, protections, or model/firmware configuration. Record first; do not assume a broken controller.
  • No live-heater, PID response, true temperature tracking, nonvolatile upload/persistence, or safety-interlock behaviour is verified by this menu-only test.
  • Share screenshots or the observations above. Update the simulator from observed controller behaviour and H185 documentation, then repeat this test on Channel 2.
  • Windows Code 28 / no COM port remains an independent IT-driver issue; direct Python communications must wait until Windows exposes the E58-CIFQ2 correctly.
