3. Cooling Load Pump #5-#6 (Remote I/O Module C – Relay 1 and Relay 2)
If the CSM will be controlling more than four cooling load pumps - Cooling Load Pump 5 Enable and Cooling Load Pump
6 Enable relay outputs are used to start and stop pumps 5 and 6. When the proper signal is sent by the CSM through the
pump digital output, the pump will start.
4. Cooling Tower Output #1–#4 (Remote I/O Module E – Relay 1, 2, 4, and 5)
The cooling tower 1–4 digital outputs are used to start and stop the cooling tower fans #1 through #4. The CSM controls
the tower stages by using the cooling tower staging control feature.
5. Cooling Tower Output #5–#8 (Remote I/O Module F – Relay 1, 2, 4, and 5)
The cooling tower 5–8 digital outputs are used to start and stop the cooling tower fans #5 through #8. The CSM controls
the tower stages by using the cooling tower staging control feature.
6. Cooling Tower Output #9–#12 (Remote I/O Module G – Relay 1, 2, 4, and 5)
The cooling tower 9–12 digital outputs are used to start and stop the cooling tower fans #9 through #12. The CSM controls
the tower stages by using the cooling tower staging control feature.
7. Cooling Tower Output #13–#16 (Remote I/O Module H – Relay 1, 2, 4, and 5)
The cooling tower 13–16 digital outputs are used to start and stop the cooling tower fans #13 through #16. The CSM
controls the tower stages by using the cooling tower staging control feature.
