2.7.10 Digital Inputs

Displays the selected programming user-defined digital notice, warning, and shutdown inputs. These inputs provide a multitude
of choices for configuring customized auxiliary inputs. See Figure 29 for a list of digital input choices. For descriptions of the
inputs listed refer to the following sections:

System Fault Warning Lamp with Digital Displays

System Fault Shutdown Lamp with Digital Displays

Status and Notice Digital Displays
There is an optional 2 input/5 output (I/O) module board available that can provide two additional digital (or analog) inputs.
The displays for digital inputs appear as shown below with Values true or false. Items shown in the display as True are active.

DIn A1 (digital input A1) standard

DIn A2 (digital input A2) standard

DIn A3 (digital input A3) standard (see note below)

DIn B1 (digital input B1) with I/O module board

DIn B2 (digital input B2) with I/O module board
All digital input selection and setup adjustments are done using SiteTech™ software. The following terms and descriptions are
part of the setup procedure.
Note:
DIn A3 digital input is factory reserved for Enclosure Temperature: High Shutdown on select Telecom units.

Enabled. This menu indicates whether or not the input is enabled. If the input is not enabled, the controller will ignore
this input signal

Inhibit Time Delay. The inhibit time delay is the time period following crank disconnect during which the generator set
stabilizes and the controller does not detect the fault or status event. The controller will ignore the input until the inhibit
time expires. If the inhibit time is set to zero, the input is monitored at all times, even when the generator is not running.
The inhibit time delay range is from 0 to 60 seconds.

Time Delay (shutdown or warning). The time delay follows the inhibit time delay. The time delay is the time period
between when the controller first detects the fault or status event and the controller warning or shutdown lamp
illuminates. The delay prevents any nuisance alarms. The time delay range is from 0 to 60 seconds.
