wiring model E1618 (Single Channel Pulsers)
Model E1618 of the LectroCount XL LED Remote Display is designed to receive a calibrated single channel pulse
output. A common application of Model E1618 is with a 100 pulses per revolution solid state single channel pulser (PN
07525) mounted onto a mechanical register using mounting kit (PN 42695). The E1618 is also compatible with any
single channel pulser that meets the required specifications listed below.
Since single channel pulsers do not have an output signal to reset the LED Remote Display, a Reset Switch Kit (PN
82592) is required for this application. The Reset Switch Kit resets the XL LED Remote Display to zero between
deliveries. To complete the installation, the installer must provide a 5 to 28 VDC external power source and a junction
box.
to wire the LectroCount XL LED Remote Display model E1618 to
a single channel pulser:
1. Install Reset Switch Kit. page 16
2. Set the junction box.
3. Route the display’s shielded cable, the pulser wires, and the wires from the
external power source into the junction box. Use the appropriate connectors.
4. Connect the display’s shielded cable wires to the following pulser and
external power source wires:
• XL LED terminal 53 (red wire) to Pulser power to External Power Source voltage (+Vo)
• XL LED terminal 54 (white wire) to Pulser signal
• XL LED terminal 56 (black wire) to Pulser ground to External Power Source ground
5. Tighten connectors and close the boxes.

Required Specifications
Single Channel Pulsers
The LectroCount XL LED Remote Display
is supplied with a 30 foot 4-wire shielded
cable with 22 gauge wire. If alternate
cabling is required, Liquid Controls
recommends a similar 4-wire shielded
cable with 22 gauge wire or larger and a
maximum cable length of 30 feet.
Shielded Cable
A jumper is required between terminal 52 and terminal 53 on the display’s J1 terminal block. Display
units from the factory will include the jumper. When rewiring, ensure that this jumper is in place.
