⚠ ⚠ ⚠
Note! The maximum load may not exceed 50 VA.
Cooling module
The cooling module is mounted in the electric cabinet on the intended rail . If there is no room, the module can be installed
in an external, enclosed cabinet and connected with a longer modular cable.
⚠
• Connect a modular cable between HP CRM Exp.out and HPC CM Exp.in
Cooling module connections:
Temperature input, T1: Sensor, cooling tank
Temperature input, T2: Sensor, coolant cooler
Temperature input, T3: Sensor, cooling tank outlet
Temperature input, T4: Sensor, cooling circuit
Analogue input 0-10 V, AI1: Signal from dew point sensor, room temperature 0 - 50°C
Analogue input 0-10 V, AI2: Signal from dew point sensor, relative humidity 0-100%
Analogue output 0-10 V, AO1: Signal to cooling circuit pilot valve
Analogue output 0-10 V, AO2: Signal to cooling fans
Relay 24 VAC, DO1: Signal to reversing valve against cooling tank (passive cold)
