Important: pump status outputs

Outputs 1-4 are available as single-pole change-over relay contacts: Relay 1, 2, 3 and 4. Connect to the normally open or normally closed contacts of the relay as required and configure the pump’s software accordingly. See 18.10 Outputs.

Note: The maximum rating on the relay contacts of this pump is 30V DC; maximum load 30W.

Note: Also suitable for low power: ie, 1mA at 5VDC minimum.

22.12 Outputs 1, 2, 3, 4

Note: Relay 1 (J14) is represented here. Relay 2, Relay 3 and Relay 4 (J15, J16 and J17) function identically.

Connect your output device to the c (common) terminal of your chosen relay connector and either the n/c termi- nal or the n/o terminal (normally closed or normally open) as required. Configure the pump’s software accord- ingly. See 18.10 Outputs.

By default, Relay 1 is configured to indicate Run/Stop sta- tus; Relay 2 is configured to indicate Direction status; Relay 3 is configured to indicate Auto/man status; Relay 4 is configured to indicate General alarm status. See 12 Switching the pump on for the first time.

22.13 Supply voltages

An appropriate voltage supply is available where required on each connector. In addition, supplies may be drawn from the Spare supplies connector (J12).

In the table below, “Max load” is the maximum total load on each supply, irrespective of the number of connections.
