4. OPERATION
IMPORTANT
NEVER OPERATE UNIT WITH FRONT PANEL UNSECURED OR WITH CASE UN- EARTHED.
With the mains off the display in top left hand of the meter will be blanked.
NOTE: Coins may be inserted under these conditions but will be lost
On applying mains the display will indicate 00. When a coin is inserted, the display will indicate time selected and the
load switched on. The display will count down in one minute steps until zero is reached when the load is switched off.
Further coins may be inserted at any time in the timing sequence and the display will indicate total time remaining.
The meter will operate up to 999 minutes (approx 16½ hours) before the meter resets to zero.
The timing circuit may be overridden by the key operated matchplay switch located below the coin mechanism. To
over-ride insert key and turn to the right. The display will be blanked and the load switched on. Any coins inserted
will be lost. On returning the switch to the vertical position the meter will be reset to the zero time condition and the
display will indicate 00.
5. REPAIRS AND FAULT FINDING
In case of failure the front panel may be removed and completely replaced or individual parts replaced. . In all cases
it is not necessary to remove the control unit from the wall.
To replace the printed wiring board simply withdraw by sliding the board out of its guides and replacement is the
reverse ensuring that the board is pushed fully home onto the stops.
The following table is a guide to diagnosing faults that may occur:
1. Replace coin
mechanism and/or switch
assembly
2. Replace main PCB
Replace main PCB
Check matchplay switch.
If correct replace main PCB
Replace main PCB
Replace main PCB
Replace main PCB
FAULT
REMEDY
Load switched on permanently
Load not switched on
Load fails to switch off after
time interval
Incorrect or erratic timing
Display fails to read 00 when
mains power applied
Replace Main PCB
Remove connectors from coin
mechanism switch assembly.
Short connectors together If
unit then switches on replace
switch assembly, if not replace
PCB.
Replace main PCB
1. Check not set for seconds
mode.
2. Check setting of timing
switch, if correct replace PCB
Replace main PCB
FAULT
REMEDY
Display indicates 00 but does
not count up
Display counts up and load
switches on but does not
count down to zero after
token inserted
Display appears to
function correctly but load
permanently on
Display blank and load
not on
Display blank and load
on
Display blank and load not
on (and coin counter fails to
function if fitted)
