Danfoss Gas Sensor DGS
Status LED / B&L:
GREEN is power on.
- flashing if maintenance needed
YELLOW is an indicator of Error.
- the sensor head is disconnected or not the
expected type
- AO configured as 0-20mA but no current is running
- flashing when sensor is in special mode (e.g. when
changing parameters with the service tool)
- Supply voltage out of range
RED is an indication of alarm due to gas
concentration level.
The Buzzer & Light behaves identical to the status
LED.
Ackn. -/Test button / DI_01:
TEST - The button must be pressed for 8 sec.
- Critical and warning alarm is simulated and AO
goes to max. (10V/20mA), stop on release.
ACKN. - if pressed during critical alarm, as default*
the relays and buzzer goes out of alarm condition
and goes back on after 5 minutes if the alarm
situation is still active.
* the duration and whether to include the relay
status with this function or not is user defined
DI_01 (terminals 1 and 2) is a dry-contact (potential-
free) behaving identically to the Ackn./Test button.
DC-supply for external Strobe&Horn
Whether the DGS is powered by 24Vdc or 24Vac,
a 24Vdc power supply (max. 50mA) is available
between terminals 1 and 5 on connector x1
