Field Engineer’s Notes (From the Trenches) The “Gotcha” is LCNP-CPU Pairing, Drop Cable Termination & Port Identification. LCNP Must Pair with Correct CPU: The 1C31150G01 is designed for the 1C31110G01 (or 1C31107G01) Drop Controllers. It will notwork as a standalone or with non-Ovation CPUs. If you replace a Drop Controller, you typically replace/swap the LCNP…
DetailsQuick Sizing & Sourcing Snapshot Manufacturer: Westinghouse / Emerson Automation Solutions (Ovation™ DCS) Part Number: 1C31110G01 System Platform: Emerson Ovation™ DCS Hardware Type: Drop Processor Module (DPM) / Controller Module — also referred to as Ovation Controller (OC) or Drop Controller Architectural Role: Plugs into Slot 0 (leftmost) of an Ovation I/O Drop rack (e.g.,…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is Sense Voltage Landing & NO/NC Configuration. Sense Voltage (TBSH Base): The 5X00121G01 does NOT generate sense voltage. You MUST land: 120V AC (Hot) or +125V DC → TBSH base SENSE (+) terminal Neutral (AC) or 0V DC (Return) → TBSH base SENSE COM (or COM) terminal…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is TBSH Base Fuse, Load Voltage Rating & SSR vs Relay Version. Terminal Base (TBSH) Fuse: Many Ovation DO installations use a user-installed ATC/ATO blade fuse (3A or 5A) on the TBSH base’s +V distribution. If alloutputs on a group or the whole module are dead (Point…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is Terminal Base Selection & TC Polarity. Terminal Base (TBSH vs Generic): The 1C31179G01 mustplug into an Ovation TBSH (Standard High Density) or TBQC (Q-Series) base — e.g., 1C31125G02 (TBSH02) or equivalent. These bases have the CJC thermistors and the Drop Bus interface. You cannot land TC…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is Terminal Base Type & 1-5V vs 4-20mA Range Setting. Terminal Block (IC200TBM001): The ALG320 itselfhas no screw terminals. You must snap an IC200TBM001 (Terminal Block Module) onto the right sideof the ALG320. It carries the field wiring (Ch1+/Ch1-/Com etc.). Newer VersaMax bases (IC200CHS006/022 with ‘T’ suffix…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is 24V DC Field Power & Sourcing Wiring. Field Power (V+, COM) on Terminal Base: The MDL740 does NOT generate its own 24V DC. You MUST land: +24V DC Supply Positive → Terminal Base V+ (or marked “+V”) screw terminal — one per group or jumper…
DetailsField Engineer’s Notes (From the Trenches) The “Gotcha” is 512KB Memory Limit, Battery & No Redundancy. Memory Limit (512KB): This is the #1 “gotcha” when migrating a program from a 772 (1MB) or 774 (2MB) to a 731. If the original project is >512KB (large symbol tables, many rungs, big %R arrays), it will not…
DetailsCustomer Value & Operational Benefits Small-Footprint Distributed I/O (Cost-Effective) The CHS398 gives you exactly 5 slots — enough for 160 discrete I/O or 20 analog channels in a space roughly half the width of a CHS392. Perfect for pump skids, weigh hoppers, or small machine annexes that need 20-80 I/O points 30-150 ft from the…
