P. BACK-STOP KIT (when ordered)
Separate back-stop installation drawings are provided with the back-stop kit.
Installer must ensure that the finished distance between the edge of carriage and
the inside of the back-stop panels does not exceed 4 inches.
Q. ELECTRICAL CURRENT SENSOR (ECS) with TRIP RELAY (Reference Fig. 40)
The ECS works with a timed, trip delay relay, which bypasses the sensor during
every motor start up. The trip delay timer is factory set for 3 seconds and is not
adjustable.
The current setting of the ECS is factory set to the motor’s full load amp nameplate
rating for the specified voltage, but must be field adjusted for specific conditions at
the installation site once all electrical control and sensing devices are wired.
NOTE: It is important that the contractor or entity overseeing the installation of this
lift ensures that the electrician has made these adjustments to the ECS to prevent
the lift from damaging itself under over-loading or jam-loading conditions.
DANGER !
Secure platform and chains! Do not remove or disconnect the motor
or brake unless the platform and chains have been secured per
“Blocking Instructions” section. Serious injury or death may result.
1. Load the carriage to the rated capacity and run the lift. Record the full load amp
draw reading of the motor with the loaded carriage.
If the motor DOES shut off within approximately 3 seconds – Go to Step 2.
If the motor DOES NOT shut off during lift travel – record the full load amp
reading and Go to Step 3.
2. Turn the power off and adjust the ECS amp rating up by turning the small amp
dial on the front of the ECS in a clockwise direction. Do not increase more than 5
amps at a time. Repeat this process until the lift will raise the rated load without
shutting off.
