Never apply mains power to the terminals within a qdos30 24V
relay module. Apply the correct signals to the terminals shown
below. Limit signals to the maximum values shown. Do not apply
voltage across other terminals. Permanent damage, not covered
by warranty, may result. The maximum load on the relay contacts
of this pump is 24VDC at 1.0A. Note that the maximum switching
capacity on DC is 30W.
Alarm output (J5)
Connect the output device to the C (common) terminal of
the relay connector and either the N/C (normally closed) or
N/O (normally open) terminal as required.
This relay coil is energised when the pump has an alarm
condition.
Note: Alarm conditions are generated by system errors.
This alarm will not be operated for analogue signal errors.
