LED Indicators
1.
ON
Power
ON
LED. Green LED turns on when power is ON. It
indicates Power On status of the unit.
2.
L – Alarm
When gas concentration exceeds low threshold level,
TS21I_IR_CO2 generates low alarm condition. For low alarm
condition, yellow LED turns ON till unit is reset.If relay1 output
is pulse type, relay remains on for 5sec. If relay1 output is
latch type, relay remains on till the unit is reset.
3.
H- Alarm
When gas concentration exceeds high threshold level,
TS21I_IR_CO2 generates high alarm condition. For high alarm
condition, red LED turns ON till unit is reset. If relay2 output is
pulse type, relay remains on for 5sec. If relay2 output is latch
type, relay remains on till the unit is reset.
3.
