18.10 Outputs

The 520DuN pump offers four relay status outputs. See 12 Switching the pump on for the first time for initial startup defaults. Each of five parameters can be config- ured to any output, or more than one output.

The parameters are:

Run / stop

Provides a status output to indicate whether the pumphead is in a running or stopped condition. When running at 0rpm, the run / stop output indicates run- ning.

Direction

Provides a status output to indicate which direction the pump is set to run in.

Auto / man

Provides a status output to indicate whether the pump is in analogue control mode or manual control mode.

General alarm

Provides an alarm output when any system error condition occurs except: leak detected; analogue signal out of range; analogue over-signal; analogue no sig- nal.

Leak detected

When used with a leak detector, this output provides an alarm when the pump has been automatically switched off following tube failure.

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 below in this section.

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