Press the left/right arrows to adjust the current time in steps
of 1 hour (this allows for adjustment due to daylight saving,
for example). Press OK. The screen reverts to the previous
mode with the addition of the flashing timer symbol. The run/
stop button is disabled as the
timer now has control.
When the start time is reached the screen shows the unit
running as normal. When the stop time is reached the display
shows stopped.
Smart Interrupter Functional Check
To check the switching function:
Switch off the Smart Interrupter and disconnect it from the
CP supply.
Connect a DMM set to measure the resistance between the
output leads, meter +ve to the Red lead and meter -ve to the
Black lead (if connected backwards the Smart Interrupter
will emit a warning tone and the resistance readings will be
erroneous).
With the unit off, the resistance measured should be greater
than 100k
Ω
. Switch the Smart Interrupter On and set it to
Stopped.
The resistance measured should now be very much less
than 10
Ω
.
Switch the Smart Interrupter Off and disconnect the meter.
Note: If the unit is set to Running, the resistance value will
fluctuate between these readings as the switch turns On and
Off. If either resistance measurement is outside the limits
stated above, the unit should be returned to Radiodetection
for service.
Smart Interrupter Maintenance
The Smart Interrupter is powered by 2 x LR20 (D-cell) batteries.
Battery level indication.
When the battery level is full the battery symbol remains black.
When the battery level becomes low the battery icon shows
a single bar. When there is no bar replace the batteries. The
battery compartment can be accessed by removing the battery
cover, as shown in the diagram.
