TEF 9980 STATUS LIGHT -
INSTALLATION AND USER MANUAL
7 FAILURE MODES
The TEF9980 constantly monitors the condition of the light by meas-
uring temperature, voltage and current. Failure is reported to control
system as described below. See also section “Lamp connections”.
Failures are grouped in two main modes; “alarm” and “warning”.
Warnings are considered to be corrected when environmental condi-
tions change. Alarms are considered to be permanent.
When light is OK, failure signal is “high”. If a failure occurs, failure signal
will go “low” and approx. every 5 seconds send out a pulse sequence
to indicate type of failure. Pulse width is 10ms and duty cycle is 0.5.
No. of pulses
