Basler Electric DGC-2020 - Manual (Page 309)

3. Max Input Voltage (V) - This setting defines the maximum valid voltage expected from the transducer
or device connected to the analog input. Voltage above this threshold will be limited to this value. The
Max Input Voltage setting can be set only when Voltage is selected as the Input Type.
4. Min Input Current (mA) - This setting defines the minimum valid current expected from the transducer
or device connected to the analog input. Current below this threshold will be limited to this value. The
Min Input Current setting can be set only when Current is selected as the Input Type.
5. Max Input Current (mA) - This setting defines the maximum valid current expected from the
transducer or device connected to the analog input. Current above this threshold will be limited to this
value. The Max Input Current can be set only when Current is selected as the Input Type.
Configuring Remote Contact Inputs on the CEM-2020 (See Figure 7-25)
Front Panel Navigation Path: SETTINGS > PROGRAMMABLE INPUTS > CONFIGURABLE INPUTS
The settings of this screen are disabled unless the CEM-2020 (Contact Expansion Module) has been
enabled as previously explained.
For each contact input, configure the following parameters:
1. Alarm Configuration - Select an alarm configuration of 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 the Alarm Configuration selection.
2. Activation Delay - This parameter defines how long 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 the oil pressure is low and the engine is
running. This type of switch will be closed when the engine is not running and it should be blocked.
However, a low oil pressure alarm or pre-alarm is annunciated when a low oil pressure occurs and
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.
