Basler Electric DGC-2020 - Manual (Page 306)

For each contact input, configure the following parameters:
1. Alarm Configuration - Select None, Alarm, or Pre-Alarm. When an alarm occurs, the horn output
annunciates with a constant beep and the engine shuts down. When a pre-alarm occurs, the horn
output annunciates with an alternating on and off beep and the engine remains running. If None is
selected, the input is status only. The status is available to BESTlogicPlus Programmable Logic
regardless of Alarm Configuration setting.
2. Activation Delay - This parameter defines the duration that the input remains on before any
annunciation occurs.
3. Label Text - Enter descriptive text that signifies the use of the input. This text appears next to the
input in BESTlogicPlus Programmable Logic and in the event log if the input is configured as an alarm
or pre-alarm.
4. Contact Recognition - Select whether the contact input should be recognized always, or only while
the engine is running. For example, a switch closes when oil pressure is low while the engine is
running. Such a switch would be closed when the engine is not running but a low oil pressure alarm
or pre-alarm should not be annunciated unless the switch is closed while the engine is running. A
selection of While Engine Running Only prevents spurious annunciation when the engine is not
running.
Configurable Programmable Functions on the DGC-2020 (See Figure 7-23)
Front Panel Navigation Path: SETTINGS > PROGRAMMABLE INPUTS > PROG FUNCTIONS
Programmable functions are pre-defined functions in the DGC-2020 and are initiated by a contact input.
An input must be mapped to a programmable function for that function to operate. Furthermore, some of
the programmable functions can be configured as alarms or pre-alarms and cause annunciation to occur
on the RDP-110 (Remote Display Panel).
