INSTALLATION
The meter meets NEMA 4X/IP65 requirements for indoor use,
when properly installed. The units are intended to be mounted on an
enclosed panel. The viewing window and buttons are factory sealed
for a wash down environment. A sponge rubber gasket and
mounting clip are provided for sealing the unit in the panel cut-out.
Installation Environment
The unit should be installed in a location that does not
exceed the maximum operating temperature and
provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.
The bezel should be cleaned only with a soft cloth and
neutral soap product. Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate
the aging process of the bezel.
Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to
operate the buttons of this unit.
The following procedure assures proper installation:
1. Cut the panel opening to the specified dimensions. Remove burrs and clean
around the panel opening.
2. Carefully slide the panel gasket over the rear of the unit to the back of the
bezel.
3. Assemble the nut fastener and mounting screw onto both sides of the
mounting clip. The tip of the screw should not project from the hole in the
mounting clip.
4. Install the unit through the panel cut-out until the front bezel flange contacts
the panel.
5. Slide the mounting clip over the rear of the unit until the mounting clip is
against the back of the panel. The mounting clip has latching features which
engage into mating features on the housing.
6. Alternately tighten each screw to ensure uniform gasket pressure. Visually
inspect the front panel gasket. The gasket should be compressed to about 75
to 80% of its original thickness. (Recommended torque is 28 to 36 in-oz.) If
not, gradually turn the mounting screws to further compress the gasket.
7. If the gasket is not adequately compressed, and the mounting screws can no
longer be turned, loosen the mounting screws and check that the mounting
clip is latched as close as possible to the panel.
Repeat the procedure for tightening the mounting screws.
APPLICATION FOR CUB4RT
Relative Temperature Error Display
A customer desires to display the difference between the actual
temperature of an oven and the desired temperature of 475.0°F. If the
temperature of the oven is 464.8°F, the display should read -10.2°F. A
Pt392 type RTD is used.
The user offset capability of the CUB4RT allows for this type of
temperature indication.
Desired oven temp = 475.0°F, set offset for -475.0. Unit will display
the temperature relative to 475.0°F.
