Usage Instructions
- Installation: Power down the main controller before inserting the DIM5.1. Align the module with the internal connector of the Deif control unit and press firmly until the clips lock into place.
- Configuration: Use the Deif Utility Software to define the logic for each input (e.g., Normally Open or Normally Closed). Assign specific functions such as “Remote Start” or “External Trip” to the corresponding channels.
- Wiring: Connect field wires to the terminal block. Ensure that cables are properly labeled and routed away from high-power AC lines to minimize signal noise.
- Testing: Once powered, trigger the field device and verify that the corresponding status LED on the DIM5.1 or the controller display changes accordingly.
Q&A – Frequently Asked Questions
Q: Is the DIM5.1 compatible with the AGC series controllers? A: Yes, the DIM5.1 is specifically designed as an expansion module for the AGC (Advanced Genset Controller) and PPM series platforms.
Q: Do the inputs require an external power source? A: Most configurations utilize the system’s internal 24V supply to wet the contacts, but check your specific wiring diagram for potential-free or powered input requirements.
Q: Can I use multiple DIM5.1 modules on a single controller? A: Yes, Deif systems allow for multiple expansion modules to be daisy-chained or slotted together, significantly increasing the total I/O count.
