Timer reset functionality
The timer for function and duration test can be set to a particular time of the
day by either pressing the test switch for longer than 10 seconds or cycling
the unswitched line supply 5 times within 1 minute. The timer adjustment
will enable the test start time to be defined manually at time in day when
the timer was reset. It will also disable the adaptive test algorithm thereby
forcing the unit to perform the test at the same time rather than it being
defined by the adaptive algorithm. This function will only work provided the
interval time is greater than zero (automatic test mode enabled). The delay
timer value set when the unit was commissioned will be reloaded in order to
randomise the tests between adjacent units.
Rest Mode / Inhibit Mode
Emergency operation is automatically started when the mains supply is
switched off. If the Rest Mode is activated, the discharging of the battery will
be minimized by switching off the LED output. If the Inhibit Mode has been
activated before the mains supply is switched off, Rest Mode will be automa-
tically activated if the mains supply is switched off within 15 minutes.
Rest Mode and Inhibit Mode can be initiated by applying a short pulse bet-
ween 9.5 and 22.5 V
DC
in amplitude for a period of 150 to 1,000 ms. This pulse
shall be applied to terminals marked Rest.
After a mains reset the EM converterLED ST exits the Rest Mode. Rest Mode
and Inhibit Mode can both be disabled by applying a voltage pulse of
1,000 to 2,000 ms to the terminals marked as Rest to send the RE-LIGHT/
RESET INHIBIT command.
