LiftMaster 90503000L5 Manuel D'instructions

APPLICATION
This modification is available for models T, APT, SD, GSD, GT and GH
Logic 5.0; or J, H, Logic 1 - 5.0 and mechanical/contactor style operators.
NOTE: Not available on model LGJ or with Hazardous Area Modification.
FUNCTIONS
A 6-digit non-resettable 24 Vac electro-mechanical counter is mounted in
the operator control enclosure. This counts the number of times the
CLOSE coil is energized on a contactor style operator. When installed on
a logic style operator, this will only count the number of cycles when the
door reaches the full open position. If a mid-stop is programmed on a
logic style operator, this will not activate the counter.
INSTALLATION
Field modifications require the use of kit 71-90503000L5. A parts bag for
both the "Logic" and "Contactor" style operators and a counter will be
provided with the field kit.
LOGIC 5 STANDARD OPERATORS (FOR MODELS T, APT, SD,
GSD, GT AND GH)
1. Disconnect power from the operator. Verify that all LEDs are OFF on
the logic board.
2. Remove the parts from the bag labeled "74-33068."
3. Remove the base off the counter by removing the two screws from
the bottom. Reuse the two screws to secure the counter to the
mounting bracket (Figure 2).
4. Using one of the crimp-on wire nuts, attach the 10" black wire with
the .187" quick-connect to one of the black wires coming from the
counter.
5. Using the remaining crimp-on wire nut, attach the 10" black wire
with the .25" piggy-back quick-connect to the remaining black wire
coming from the counter.
6. Locate the limit switch, lock washers (2), metal nut plate (1), metal
back plate (1), and pan head #4-40 screws (2). Install the limit
switch on the mounting bracket (Figure 2). Be careful to line up the
limit switch with the open limit switch (OLS).
7. Remove the terminal block L1, L2 and L3. Note that certain
operators have the terminal block mounted on a flange. Remove
flange from electrical box if present. This flange will not be reused.
8. Attach the terminal block to the new limit switch bracket (provided)
using screws and lock nuts from the previous step.
9. Only operators without the terminal block mounting flange will
require the L1, L2 and L3 spade connectors be bent and made flat.
Using needle nose pliers, remove the wires from the spade
connectors and mount the terminal block on the new limit switch
bracket. Bend the 3 spade connectors (Figure 3) and install wires
back on the connectors. NOTE: Not all installs require this step.
10. Install mounting bracket (with counter and limit switch attached) to
electrical box (Figure 2). Adjust the limit switch to align with the OLS
so that it will activate just before the OLS activates.
(FOR MODELS H AND J, STANDARD AND DAMP ENVIRONMENT)
1. Disconnect power from the operator. Verify that all LEDs are OFF on
the logic board.
2. Remove the parts from the bag labeled "74-33068."
3. Using one of the crimp-on wire nuts, attach the 10" black wire with
the .187" quick-connect to one of the black wires coming from the
counter.
NON-RESETTABLE COUNTER
To prevent possible SERIOUS INJURY or DEATH from
electrocution, disconnect electric power to operator BEFORE installing.
ALL electrical connections MUST be made by a qualified individual.
