Wiring
Power supply
All power supply wiring must be sized and selected
according by the project engineer in accordance with the
national electrical code.
Warning : to prevent injury or death, disconnect elec-
trical power source before completing wiring connec-
tions to the unit.
Control
UCM provide :
- Alarm, running, max. capacity output
- Remote emergency stop
- External circuit lockout
- Ice making option
- External chilled water setpoint
- External current limit setpoint
Connection are shown in the field diagrams which are
shipped with the unit.
Remote clear language display
The remote CLD is intented for indoor use and is not weath-
reproof. It is mounted in a molded plastic display box with
a molded keypad. Aithough this is not the same as the
membrane keypad of the unit's CLD, the key locations and
labels are identical
Communication link wiring must be 1.5 mm
2
shielded,
and not exeed 1500m for each link.
Remote CLD Mounting
All hardware (tools, screws,etc...) is to be field supplied. Fig-
ure 11 shows the remote CLD panel and the electrical access
knockouts at the bottom and top of the panel. Remove the
knockouts that will be used for wire entry, prior to mount-
ing the panel.
Note : On the back of the panel is a knockout for an
electrical outlet box, if one is to used.
Prior to mounting the panel, the actual microprocessing
board needs to be carefully removed and set aside. To
remove the board, open the protective door that cover the
keypad. Remove the cover plate at the bottom of the key-
pad, by loosening the screw on the cover plate.
After removing the cover plate, remove the four srew that
secure the keypad (one in each corner). The keypad can now
be lifted out the display box.
Mark the location of the mounting holes, remove the box
and drill the necessary holes in the surface. Put the dis-
play box back in position and secure it to the mounting
with the required screws.
The microprocessing board can now be replaced in the
display box with its four attaching screws.
