LT3500 Installation and Operating Instructions 1
Introduction
Operational Features
The LT3500 incorporates a programmable current sense facility which stops the timer
counting down when the connected appliance is turned off. This is particularly useful
with applications such as air conditioning and heaters in apartments and community
halls where the user may turn off the heating or cooling when vacating the premises.

2 LT3500 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 LT3500 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.

Service Mode
The service mode consists of thirteen settings split in to four functional areas:-
1. Programming current sense values
2. Programming credit
3. Audit functions
4. Other functions
To access service mode remove the coin box, press and release button B (Figure 4) to
step to the desired setting number (St.01 to St.13). Simultaneously pressing and
releasing both buttons A and B will step back to the previous setting. On reaching the
required setting number press button A to enter desired values.
Figure 4 - Front Panel
Programming current sense values
For the LT3500 to operate successfully the current consumption of the load must be
programmed at installation. It is recommended that the appliance is turned on and the
current monitored in both idle (low current value) and “in use” (high current value)
modes using setting St.11. With air conditioning units in particular it is advised to
check if there is an intermediate stage where the appliance has stopped cooling or
heating but enters a shut down mode which consumes current. This current should be
used as the idle current. The LT3500 should then be programmed for “in use” current
values and idle current values using settings St.13 and St.12 respectively.
St.11 Real time current reading
Press and release button B to step to setting number St.11. Press button A to enter
setting. The display shows a real time current reading in hexadecimal format (see

the following messages initially: -
no.in There is no reply from the sensor (timer can not function correctly)
in.lo The value from the sensor is below the trigger level setup in ST.12.
trig The value from the sensor is above the trigger level setup in ST.13.
Press button A to switch to current display mode, this will show "i-xx", where xx is
the current reading as a value in hexadecimal format (see appendix 1); this value will
change as the load current consumption varies.
St.13 High current (In Use) Value
Press and release button B to step to St.13. Press button A to enter setting. Once
entered this mode will turn on the relays and the display will show "H-xx" to indicate
the stored hexadecimal setting for the high current mode. To learn a new current value,
set the load into its minimum high power state then press button A and wait as the
timer counts down from 8 to 0, with the display showing "C-xx", where xx is the count
down in seconds. If the value exceeds, equals or is just too close to the low value then
an "Err " will be displayed and no changes will be made; when a good value is
accepted it will be stored as the new setting. The display will return to showing the
current hexadecimal value for the high power state.
St.12 Low current (Idle) value
Simultaneously press and release both buttons A and B to step back to St.12. Press
button A to enter setting. Once entered this mode will turn on the relays and the
display will show "L-xx" to indicate the stored hexadecimal setting for the low current
mode. To learn a new current value, set the load to its idle state then press button A
and wait as the timer counts down from 8 to 0, with the display showing "C-xx",
where xx is the count down in seconds. If the value exceeds, equals or is just too
close to the high value then an "Err " will be displayed and no changes will be made;
when a good value is accepted it will be stored as the new setting. The display will
return to showing the current hexadecimal value for the low power state.
Programming credit
The credit functions allow the meter to be programmed for fixed time, session time or
session cost for charging purposes. Additionally a factory set option allows a
combination of session time and session cost. Once the initial cost is met further coins
will add time allocated to that coin. This is referred to as top-up mode.
Press and release button B to step to the desired setting number.
When the required number is showing on the display press and release button A to
display the existing setting. Press and release button A to select the digit to be changed
then press and release button B to alter that digit.
NOTE
Coins and tokens are validated by two coin sensors. Coin 1 sensor validates £1 coins,
L2 and L4 tokens. Coin sensor 2 validates €1, €½, 10p, 20p, L1 token

Appendix I Hexadecimal
The value of the current being consumed by the appliance displayed by the LT3500 is
expressed in hexadecimal which is base 16. Humans use a base of ten (decimal) but
computers often use other bases such as two for the binary system. With base 16 the
characters representing numbers are zero to the letter F (0123456789ABCDEF). i.e.
the decimal value for '1' is represented in hexadecimal as '1' but the hexadecimal value
of decimal 15 is shown as 'F' and the value of decimal 17 is '11' in hexadecimal.
