3.7.5 User Inputs / Customer Inputs
The user can connect and specify up to four inputs depending on unit configuration. The user
inputs/customer inputs are digital inputs that influence the operating mode of the unit depending on
the selection. The customer input configuration settings are in the Service menu under Set Alarms,
Screen 2 of 7. The choices for the customer inputs are shown in Table 7 along with their associated
reaction. A terminal strip is provided in the cooling unit to connect your contact closure to. You have
the ability to set the control to react on an open or closed contact.
NOTE
To enabled/disabled, delay activation and set event type (alarm, warn, message) see Event
