| Technical specification | Collective failure indication for water chillers as well as for units without relay K68. When a failure is happening at the unit, an alarm gets activated (details see in the unit's manual) The unit alarms which switch on the horn can be connected externally as a collective failure indication. Therefore, an additional 230V relay (K54) with potential free contacts is installed in the unit. The collective alarm is wired on 3 terminals (No.51, 52, 53). When there is no alarm, the contact is closed over the terminals 51 and 52. In case of failure, the relay closes the contact over the terminals 51 and 53 (opens between 51 and 52) |
