ENVIRONMENTAL INFORMATION
European Directives 2002/96/EC and 2003/108/EC require
that the equipment bearing this symbol on the product an/or
its packaging must not be disposed of with unsorted
municipal waste. The symbol indicates that this product
must be disposed of separately from regular household
waste streams. It is your responsibility to dispose of this and
other electric and electronic equipment via designated
collection facilities appointed by the government or local
authorities.
IMPORTANT WARNING NOTES
1. The pulse transmitter MUST NOT be used to measure petrol
or other flammable liquids.
2. It is designed for use with diesel, gas oil, hydraulic oil and
heating oil.
3. It must not be sited adjacent to a petrol dispenser or in any
other hazardous zone.
4. Installation of this equipment should be carried out by a
qualified fuel installation engineer.
5. The installation must conform to all relevant electrical and
local authority regulations and standards.
PRODUCT DESCRIPTION
The Pulse Transmitter utilizes advanced CMOS technology to
achieve a multi-channel solution to the problems of parasitic
pulsing associated with single channel pulse transmitters. The
device requires minimal supply current, accepts a wide supply
voltage range and has a large output current sink capacity as well
as an option for volt-free output contacts via a plug in reed relay.
The Pulse Transmitter has been designed to maximize the amount
of disc rotation available without false generation of pulses
resulting in a vast improvement over conventional single channel
solutions.
PULSE OUTPUT
PULS.800: 10 pulses per litre

INSTALLATION
1. Remove meter front cover, dial face, register.
2. Remove the bevelled pinion gear
3. Place the nylon washer over the protruding gear shaft before fitting the
modified bevel gear with the slotted disc fitted.
4. Remove the bottom two meter bolts. See photo 1 on page 4.
5. Ensure that the meter inlet/outlet ports are in the desired orientation. If
not then turn the meter backplate to the desired position before
proceeding.
6. Fit the pulser using the M6 bolts, washers and nuts supplied. Ensure
that the bracket is pushed fully downwards before tightening bolts. See
photo 2 on page 4.
7. Ensure the slotted disc is centrally located between the pulser emitter
and receiver and does not rub on either. See photo 2 on page 4.
8. Refit the register.
9. Drill a 12mm hole in the meter cover in the location shown on the
pulser location diagram and photo on page 5. Fit the TA.GLND as
shown.
10. Slide signal flex through gland leaving 140mm of flex inside the meter
casing. Tighten gland and carefully refit meter front cover and dial face
insuring signal flex is coiled up inside casing without being snagged or
pinched.
11. Connect pulser wires as per connection diagram on page 6.
12. Ensure that the pulser functions correctly and check that when the
meter is reset it doesn’t clock up extra pulses.

Connect the pulse transmitter as shown in the connection diagram.
The connections are rated as follows:
Supply Ratings:
Voltage - 5 -12V DC
Current - 5 -40 mA
Passive Contact Ratings:
Voltage - 24V DC Max.
Current - 1A Max.
Power - 15W Max.
NB: The pulse transmitter pulse input and output (green and
yellow) wires are connected across the passive contacts of the
transmitter relay. If the key system, to which the transmitter is to
be connected, has only 3 wires (0 volts, +volts and “signal”) the
transmitter 0V (black) and the yellow pulse wire can be linked
together. The key system +volts can then be connected to +V
(red), 0 volts to 0V (black) and “signal” to the green pulse wire.
This will “drag” the signal down to 0 volts every pulse.
