Additional board for upgrading Wilo-CR-<br />
System switchgear series for individual run /<br />
single fault signals for single and twin-head<br />
pump systems.<br />
>Function<br />
- Potential-free signal contacts for operation<br />
(NO contact) and fault (NC contact) of:<br />
pump 1, pump 2, frequency converter<br />
- Signalling the digital inputs DIG2 or DIG3,<br />
e.g. frost (heating) or low water (pressure<br />
boosting)<br />
- Analogue output for actual speed value or<br />
actual-value transmitter (can be preselected)<br />
Fixing sundries and CAN-bus cable are<br />
included in the scope of delivery.<br />
Additional board for upgrading Wilo-CR-<br />
System series switchgears for individual<br />
run / single fault signals for three- to sixpump<br />
systems (signalling board 1 – 2 also<br />
required).<br />
>Function<br />
- Potential-free signalling contacts for operation<br />
- (normally open contact) and malfunction<br />
(normally closed contact) of:<br />
pump 3, pump 4, pump 5, pump 6<br />
Fixing sundries and CAN-bus cable are<br />
included in the scope of delivery.<br />
