Additional board for upgrading Wilo-CR-
System switchgear series for individual run/
single fault signals for single and twin-head
pump systems.
>Function
- Potential-free signal contacts for operation
(NO contact) and fault (NC contact) of:
pump 1, pump 2, frequency converter
- Signalling the digital inputs DIG2 or DIG3,
e.g. frost (heating) or low water (pressure
boosting)
- Analogue output for actual speed value or
actual-value transmitter (preselectable)
Fixing sundries and CAN-bus cable are
included in the scope of delivery.
