2 JSGCT30 Installation and Operating Instructions
1) Unlock the front cover of the meter and lift
upwards slightly and away from the wall bracket
(see Figure 2). Unplug the cover flying lead from
the wall bracket and remove front cover.
2) The JSGCT30 should be mounted on a smooth
vertical wall making sure access to the side coin
entry is not obstructed. Take care to mount the case
level in both the vertical and horizontal axes;
failure to do so may prevent the coin mechanism
from operating correctly. Mark positions of the
mounting holes using the wall bracket as a template
and drill suitable holes in the wall. For solid
masonry use a 7 mm masonry drill bit and plug
holes with wall plugs sufficient for 38 mm long
screws. For wooden surfaces use a 3.5 mm drill bit
and screws of a minimum length of 15 mm; longer
screws are advised for very soft
surfaces. Fit the top two screws to the wall leaving the head of the screw
approximately 7 mm from the surface. Hang the wall bracket on the wall, check that
the bracket is level and tighten the screws. Fix the bottom of the wall bracket to the
wall using the two remaining screws.
3) The timer will require a fused double
pole switch for the mains input. Wire the
unit as shown in Figure 3 using
appropriately rated and approved cable
conforming to the relevant regional
standards. The meter can either be
connected to the supply via a cable fed
through the hole at the bottom left hand
side of the wall bracket or through the
back of the meter. Ensure the cables are
secured underneath the cable clamps.
4) Plug the flying lead from the cover to
the connector located in the wall bracket
and fit the front cover onto the wall bracket, drop down slightly and lock into place.
5) Apply power and the meter will briefly show ‘Pxx.x’ then any credit remaining
where xx.x is the version number of the firmware and should be quoted if requesting
technical assistance.
IMPORTANT: PROTECT THE INPUT BY A FUSE RELEVANT TO THE LOAD

Re-settable Money (Token) Counter
When the coin box becomes full, the message ‘COLL’ (collect) is displayed.
Upon removal of the coin box the display will automatically show the resettable
money counter. This shows how much money has been inserted into the meter since
the last collection. When the coin box is reinserted, the money counter will
automatically zero before displaying the remaining credit.
Note: To prevent the money counter from zeroing, insert the coin box with ‘B’ pressed
To clear any Remaining Credit

Operating Instructions
To Operate Meter
Insert coin/token. The display will briefly show ‘Coin’. The display will then show the
remaining credit. If the credit is greater than one hour it will be displayed in hours &
minutes, e.g.; 2 hours will be displayed as ‘02:00'. If the credit is less than one hour it
will be displayed in minutes & seconds, e.g.; 40 minutes will be displayed as ‘40:00'
and an indicator will flash on the display to show this (Figure 4).
If the meter is fitted with the optional key override switch then inserting the key and
turning clockwise will switch on the load, disable timing and display “FrEE”. This
action will also clear any remaining credit. To return to normal operation insert key
and turn counter clockwise.
Error Messages
Thirteen error messages are displayed to help fault finding in the unlikely event of
meter malfunction. Error messages are displayed in the format Er.xx
Er.01 Opto 1 detected an object not conforming to the required parameters.
Opto 1 is the coin sensor used to validate £1 coins, L2 & L4 tokens. If the
sensor detects that the coin is the wrong size it will show the error message.
Er.02 Opto 2 detected an object not conforming to the required parameters.
Opto 2 is the coin sensor used to validate 20p, 10p, €1, 50c coins or L1
