Operation of the Unit:
With the panel service switch ON, engage the Key-switch. The circuit will activate and the panel Green LED will
illuminate to indicate that the water services to the testing restroom are active. After turning a switch OFF, it will be
necessary to re-engage the Key-switch in order to reactivate the services. The Red LED will illuminate when the
circuit is OFF.
Pressing the panic button will deactivate the services. All Panel lights should illuminate with Panic.
Once in the Panic Mode the Key-switch must be engaged in order to reactivate service. The Alarm Signal must be
withdrawn prior to reactivation.
This unit utilizes latching solenoids that pulse ON with circuit active to open the water supply and pulse OFF with
circuit inactive to close it. Where provided, secondary solenoid(s) are provided that pulse ON when inactive in
order to provide drain-down of supply piping.
Equipment Maintenance:
The DLA Series Controller should have semi-annual inspections.
ISIMET
recommends that you periodically conduct a brief test of the system to verify that the output circuit
performs as intended.
If examination of the unit indicates tampering,
ISIMET
recommends that you first review the installation and
wiring portions of this manual prior to placing the unit in service.
ISIMET
recommends that piping systems be thoroughly flushed and cleaned and tested for leaks prior to
placing the system into use. Periodic testing of these solenoids will assure that the piping system continues to
function properly.
If you have any questions regarding the operation and maintenance of the DLA 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 (PCB) is sensitive to dust and other air-borne particles. Do not expose the interior
compartment of the enclosure to dust. 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,
ISIMET
recommends that you check the power supply to the unit. With the control
switch in the ON position, LED Fuse 1 should illuminate. If not, check the service breaker and PCB fuses.
If the fuse is not damaged and the unit still does not function, contact ISIMET or your local Service Representative.
CAUTION:
ISIMET DOES NOT recommend that service to emergency and/or safety devices, such as emergency
showers and eyewashes, be controlled by the DLA Controller System or Solenoids. Such devices are
intended to operate independent of restrictive authority operation, as is the case with the design of this unit.
ISIMET makes available components for the monitoring of such safety devices. Please contact ISIMET
regarding any questions regarding this type of application.
