This section describes the procedures for installing the UMC600 indicator, including connecting the load cell,
digital input and serial communications cables to the indicator. Instructions for CPU board replacement are
included, along with assembly drawings and parts list for the service technician.
Use a wrist strap to ground yourself
and protect components from
electrostatic discharge (ESD) when
working inside the indicator.
2.1 Unpacking and Assembly
All indicators are configured and tested prior to
shipment to ensure that they are fully functional.
Immediately after unpacking, visually inspect the
UMC600 to ensure all components are included and
undamaged. The shipping carton should contain the
indicator, tilt stand, the manual, and a parts kit. If any
parts were damaged in shipment, notify Condec and the
shipper immediately.

connector and cord grips for communications cables.
the enclosure must be opened to connect the
communications cables.
The UMC600 has no on/off switch.
Before opening the unit, ensure the
power cord is disconnected from the
power outlet.
Ensure power to the indicator is disconnected then
remove the screws that hold the front bezel to the
enclosure body. Place the indicator face-down on an
antistatic work mat, then lift the enclosure away from
the front bezel. Set the enclosure aside.
2.3 Cable Connections
The UMC600 provides a load cell connector and three
cord grips for cabling into the indicator; one for the
power, and two to accommodate communications,
digital input, and analog output cables.
One of the two free cord grips comes with a plug
installed to prevent moisture from entering the
enclosure. Depending on your application, remove the
plug from the appropriate cord grip and install cables as
required.
