UNIT REMOVAL PROCEDURE
To remove a NEMA 4X/IP65 or standard unit from the panel, first unscrew
and remove the panel latch screws. Insert flat blade screwdrivers between the
latch and the case on the top and bottom of the unit so that the latches disengage
from the grooves in the case. Push the unit through the panel from the rear.
REMOVING BEZEL ASSEMBLY
The bezel assembly must be removed from the case to install or replace
output modules, to select the input sensor type, or to set the 115/230 VAC
selector switch. To remove a standard bezel assembly (without bezel securing
screws) press the latch under the lower bezel lip and withdraw the bezel
assembly. To remove the sealed NEMA 4X/IP65 bezel assembly, loosen the
two bezel securing screws until a slight “click” is felt (the screws are retained
in the bezel) and withdraw the assembly. It is recommended to disconnect
power to the unit and to the output control circuits to eliminate the potential
shock hazard with the bezel assembly removed.
Note: The bezel assembly contains electronic circuits which are damaged by
static electricity. Before removing the assembly, discharge stray static
electricity on your body by touching an earth ground point. It is also
important that the bezel assembly be handled only by the bezel itself.
Additionally, if it is necessary to handle a circuit board, be certain that
hands are free from dirt, oil, etc., to avoid circuit contamination which may
lead to malfunction.
INSTALLING BEZEL ASSEMBLY
To install the standard bezel assembly, insert the assembly into the case
until the bezel latch snaps into position.
To install the NEMA 4X/IP65 bezel assembly, insert the assembly into the
case and tighten the bezel screws uniformly until the bezel contacts the case
and then turn each screw another half turn to insure a watertight seal (do not
over-tighten screws).
Note: When substituting or replacing a bezel assembly, be certain that it is
done with the same model using the same Output Modules. Damage to the
controller may result if the unit’s output modules are not the same. A NEMA
4X/IP65 and a standard bezel assembly are NOT interchangeable.
