Chromalox 2104 Technical Manual 59
The 2104 controller gives you two different options for
actuation of any one of several field-selectable
controller functions:
1. A Digital Input that is hardwired to terminals 1
and 2 of the controller.
2. The AUX pushbutton located on the controller
front faceplate.
You may choose to use either the Digital Input or the
AUX pushbutton, but you cannot use both.
Digital Input
The Digital Input allows you to use a remote switch,
pushbutton or contact to perform any one of seven
possible functions:
•PID1/PID2 Switch •Output Disable/Enable
•SP/AUX Setpoint Switch •Ramp/Soak
•Local/Remote Setpoint •Alarm Reset
Switch
•Auto/Manual Control Switch
The external switching device is connected to the
controller Digital Input at terminals 1 and 2 (see page
10 for wiring instructions). The Digital Input function
is selected in the CTRL PAGE programming.
When the Digital Input is used, the AUX (Auxiliary)
LED on the controller front panel is used for
indication of the Digital Input function.
