Application:
The ISIMET Laboratory Service Panel operates as a
single output controller incorporating either a solenoid valve
assembly or electrical contacts along with the digital switching
mechanism within a single enclosure. An internal junction box
houses the 120-vac line voltage along with transformer and
circuit board.
The junction box is provided with an internal
switch and fuse. A secondary j-box within this box isolates the line
wiring from low voltage output and control wiring. A polarized plug
located at the base of the junction box permits connection of the
switching circuitry on the door panel to the circuit board. The
junction box features a two-sided opening with cover that
facilitates ease when field wiring the unit. Once this cover is in
place, an isolation barrier between the mechanical piping system or
contactor and the electrical components is achieved.
Variations:
Solenoid - The unit is equipped for either natural
gas or fluid system applications (domestic water). This unit
features a manual shut-off valve with a 24-vac N/C solenoid with
fittings. The solenoid is pre-wired to the output circuit at the
printed circuit board. Refer to ISIMET Solenoid Specification for
valve specifics. Sizes from ½” – 1” IPS. All units are provided with
rubber grommets – Standard.
Electrical - Either a three (3) pole definite
purpose contactor from 30 – 50 amp, or a four (4) or eight (8) pole
mechanically held lighting contactor is provided within the
enclosure.
Enclosure Features:
Door Lock – All units are provided with a key door
lock
Operation - Key Switch - Momentary switch for an
“ON” Cycle
Control Switch – Activates the output circuit with keying for “ON”.
Push Button Switch - Momentary contacts disengage
the system requiring re-keying to active “ON”.
Panic Notification – The unit is equipped with a
“Panic” output circuit that can be utilized as a notification signal
to an alarm system. Circuit can be field configured as a dry-contact
or as 24-vac output.
LED Indicators – A Green “ON” or active LED
illuminates with service “ON”, A lower Red LED indicates that
“Panic” has interrupted service and the notification circuit is
active. Standard Units are Flush Mounted W/ White Powder Coat Door
Dual Output Circuit Option:
The unit is available as a dual output system
where the second output controls a 24-vac device that is remote of
the Service Panel. With this optional second output, the monitoring
circuit is an optional add-on with adjustable time delay “ON” and is
provided in a separate junction box at the base of this enclosure.
Door Panel Labeling:
Single Output Solenoid Systems are label per
Enclosure Style ie. “NATURAL GAS SERVICE PANEL”
Electrical Panels are labeled per amp rating of
contacts ie. “30 AMP ELECTRICAL SERVICE PANEL”
Dual Output Systems may be labeled “LABORATORY
SERVICE PANEL” (Standard).
Custom labeling for specific applications is available.
