Equipment Maintenance

The Utility Controller should have semi-annual inspections.

ISIMET recommends opening the service panel and turning OFF the control switch prior to long
periods of inactivity in the building.

Prior to anticipated activity within the building, ISIMET recommends that you conduct a brief test
of the control system by performing Start-Up Test Procedure A and Step 1 of ProcedureB.

If examination of the unit indicates tampering, ISIMET recommends that you first review the Start-
Up Checklist, then conduct ALL Start-Up tests.

ISIMET recommends that the door panel key be kept in a secured location. The door panel key
should be available only to those needing access to the interior of the unit for the purposes of
maintenance or service.
ISIMET recommends that the door panel remain locked unless service is
performed.
If you have any questions regarding the operation and maintenance of the RLA Controller, please
contact an
ISIMET Service Representative.
The enclosure has a NEMA 1 rating. It is not intended for use in wet areas. Exercise caution to prevent
exposure of the interior compartment of the enclosure to moisture. If moisture is present within the
enclosure,
ISIMET recommends that the control switch be turned OFF, power be disconnected from
the unit until the source of the moisture is determined, and all moisture is removed from the
compartment.
The electronic controller (PLC) is sensitive to moisture, dust, debris and other air-borne particles. Do
not expose the interior compartment of the enclosure. During the semi-annual inspection, if dust or
other material is present,
ISIMET recommends that you remove all foreign matter before operating the
unit.
If the Unit fails to operate, we recommend that you check the power supply to the unit. With the
control switch in the
ON position, the PLC “PWR” light should be illuminated if power is on to the
unit. If not, check the service breaker.
If the unit still fails to operate, we recommend that you contact your local Service Representative.
Removing the Door Panel
Before removing the Door Panel, turn power
OFF at the control switch, then disconnect the plug from
the terminal within the enclosure.
Follow steps 1 – 4 in reverse as shown in Figure 6.
