Q1: What is the primary function of the 3500/32M?
It is a 4-Channel Relay Module that provides four independent relay outputs for alarm and shutdown logic in the 3500 machinery protection system. Each output can be independently programmed to perform voting logic using Alarm Drive Logic with AND/OR combinations of Alert, Danger, Not-OK, or PPL inputs from any monitor channel in the rack .
Q2: Where can the 3500/32M be installed in the rack?
The module can be placed in any slot to the right of the Transient Data Interface (TDI) module. It occupies one full-height front slot and requires one full-height rear slot for the I/O module .
Q3: What is the difference between the 3500/32M and the standard 3500/32?
The 3500/32M is the M-series (Machinery Management Inside) version, which includes enhanced functionality for integration with System 1 software. The standard 3500/32 is the non-M version. The 3500/32M is the recommended choice for applications requiring online condition monitoring capabilities .
Q4: What are the common causes of channel alarm LEDs staying illuminated?
Common causes include:
Relay coil failure or stuck contact: Cycle the channel's programmed logic in the configuration software and check for continuity across relay contacts
Programming/voting logic misconfiguration: Re-verify the Alarm Drive Logic setup in the 3500 Rack Configuration Software
Backplane communication fault: If TX/RX LED is not flashing, reseat the module and check adjacent modules for the same symptom
Q5: What spare parts are available for the 3500/32M?
Key spares include:
125720-01: Spare 4-Channel Relay I/O Module (for standard applications, available for repair only)
125720-02: Spare 4-Channel Relay I/O Module (for hazardous area and functional safety systems)
149986-02: Spare 4-Channel Relay Control Module (main card)
