1. GENERAL LIMIT SWITCH REPLACEMENT
There are several limit switches installed in the platform and carriage. The switches are hard-wired to
their harnesses at the factory, but can be replaced in the field. Replacement switches are supplied with
three wire leads (pigtails). Use this procedure to wire a replacement switch into a harness.
WARNING!
•• WEAR PROTECTIVE CLOTHING AND EYE PROTECTION AT ALL TIMES. BAT-
TERIES CONTAIN ACID THAT CAN BURN. IF ACID COMES INTO CONTACT
WITH SKIN, IMMEDIATELY FLUSH AFFECTED AREA WITH WATER AND WASH
WITH SOAP.
•• WORK IN A PROPERLY VENTILATED AREA. DO NOT SMOKE OR USE AN OPEN
FLAME IN THE VICINITY OF BATTERY.
•• DO NOT LAY ANYTHING METALLIC ON TOP OF BATTERY.
a. Disconnect positive battery cable at vehicle battery compartment.
b. Note colors of wire leads on switch to be replaced (red lead and blue lead, red lead and yellow
lead, etc). Cut leads close to switch body. Strip a ¼” of insulation off remaining leads.
c. Cut wire leads on replacement switch to an appropriate length; cut leads long if unsure of exact
length. Strip ends of wires ¼”.
d. Place a 1" length of ¼” shrinkable tubing around each switch wire if you are going to solder the
new connections. Slide tubing away from end of wire.
e. Connect each harness lead to appropriate lead on replacement switch. [Contact Ricon Product
Support if replacement switch leads are a different color than switch being replaced.] The leads
can be joined with crimp-on butt connectors, or soldered.
f. Verify integrity of each connection by attempting to pull it apart.
g. Slide the shrinkable tubing over soldered connections and shrink with a heat gun.
h. Cut unused switch lead close to switch body.
i. Remove original switch from its bracket and mount replacement switch in its place.
j. Refer to appropriate Switch Adjustment section in this chapter and set switch position.
k. Reconnect positive battery cable at vehicle battery compartment.
2. ELECTRONIC CONTROLLER REPLACEMENT
The electronic circuitry inside the controller box receives command inputs from the pendant. It also
monitors and controls all lift functions. There are no parts in controller that can be replaced in the field;
the entire controller must be replaced if at fault. Verify that replacement controller is appropriate for the
application being worked on.
CAUTION!
The electronic controllers used in the various Ricon Mirage models are visually similar
and physically interchangeable. However, their programming and internal circuitry are
different, and they must not be installed in a lift they were not designed for.
a. Fully deploy lift.
b. The controller is taken out of carriage from below on some models (through access hatch), but
can be removed from above on others.
WARNING!
THE SERVICE ACCESS PANEL IS HINGED ALONG THE REAR EDGE AND SHOULD
BE HELD UP WHILE REMOVING THE RETAINING SCREWS AT THE FRONT EDGE.
THIS WILL PREVENT PANEL FROM FALLING AND CAUSING INJURY OR DAMAGE
c. To gain access to underside of lift, hold service access panel up, remove two retaining screws
and lock-nuts from front edge of panel, and lower panel.
d. Disconnect three harness connectors from controller.
e. Remove two Phillips screws fastening connector-end of controller to its mounting bracket.
