TP-6694 7/1858 Section 2 Operation
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 2-20 for a list of
digital input choices. For descriptions of the inputs listed
refer to the following:
D 2.4.5 System Fault Warning Lamp with Digital
Displays
D 2.4.6 System Fault Shutdown Lamp with Digital
Displays
D 2.4.7 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.
D DIn A1 (digital input A1) standard
D DIn A2 (digital input A2) standard
D DIn A3 (digital input A3) standard (see note below)
D DIn B1 (digital input B1) with I/O module board
D DIn B2 (digital input B2) with I/O module board
All digital input selection and setup adjustments are done
using SiteTecht 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.
D Enabled. This menu indicates whether or not the
input is enabled. If the input is not enabled, the
controller will ignore this input signal.
D 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.
D 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.
