Installation
F. An auxiliary contact is available for the Model 505.120, 505.150, or
505.180 HPUs. This contact can be used to control an external device
such as a warning lamp or a remote cooling circuit.
This contact has two adjustment parameters. One controls the polarity
of the active states of the contact: Normal (active high) and Reverse
(active low). The other parameter controls whether the contact is active
whenever a pump motor is running (Aux Contact: On/Off) or
whenever a pump motor is running and the temperature of the
hydraulic fluid in the reservoir reached the trip temperature (Aux
Contact: On/Off/Temp).
– Press the Aux Polarity: button to display Aux Polarity: Normal to
cause the contact to close when it is active.

cause the contact to open when it is active.

activate the contact when at least one pump motor is running, and to
deactivate when no pump motors are running.
– Press the Aux Contact: button to display Aux Contact: On/Off/Temp
to activate the contact when at least one pump motor is running and the
fluid temperature in the reservoir is above the temperature trip level
and to deactivate the contact when either the temperature is lower than
the temperature trip level or no pump motors are running.
– Press the Press to Set Aux Temp button to display the trip temperature
setup controls.
Press the up arrow to increase the trip temperature level.
