Heating rate controller / engineering reference

Interactive wiring explorer

Explore the proposed electrical relationships on the actual cabinet photograph. Select a circuit and channel, inspect highlighted components, then review the original D12 net schedule. This is an engineering planning aid, not an approved point-to-point installation drawing.

ARCHIVED PHOTO GUIDE · NOT CURRENT WIRING
Historical October 2026 construction record. This D12-based photo guide is not a current installation or servicing reference. Use the R1.2 electrical drawings and current connection schedule. For printed, individual FROM → TO physical wire routes use the revised workshop register. The old D12 net/photo paths are still design-review visuals. The cabinet has 3 outgoing mains L and 3 outgoing N destinations in total (plus incoming, selector-output and PE wiring); 3 reported gated +24 V and 3 common 0 V take-off positions per channel. The Crydom +3/EAO COM positive and Crydom −4/ACTIVE−/Weidmüller 13 junctions were user-reported, not inspected; EAO ENABLE LED+ is separately supplied by EN1/EN2.

Inside the cabinet

Photograph taken before the PSU relocation. Select a circuit and follow its proposed A→B connections directly on the photograph. Device outlines indicate approximate locations, never individual physical terminals or cable routes.
Layout and wiring not final. The Mean Well PSU needs relocation for clearance. Several components and the actual terminal-block identities have not been fully checked. Never use the photograph to determine terminal numbers or wire routes.
Inside of un-wired dual-channel heater controller enclosure: upper Finder relays and terminal strips, right-side Mean Well PSU, lower two Crydom SSRs and Lovato C16 breakers

Use the connection-map arrows to trace proposed links. A/B identify devices, not exact terminals. Door-mounted devices and unverified terminal positions remain explicitly off-photo. No physical cable routes are shown.

Review D12 electrical system / terminal schedule, the 11-sheet D12 drawing set and outstanding validation requirements before producing a released wiring drawing. The installed terminals, relay socket suffixes, selector contact stamps and PE arrangements must be verified directly.
