GG-2
General Description
Installation
The GG-2 control panel is a two-channel controller designed to accept two
4/20 mA input signals. It has a 24 VDC regulated power supply to power all
industry standard 4/20 mA gas transmitters and audible/visual devices.
The GG-2 control panel provides continuous real-time monitoring of each
sensor.
The backlit LCD display provides an at-a-glance status of gas concentrations
and alarms.
The GG-2 control panel is assembled into a wall mounted enclosure
designed for non-classified locations. The gas sensors (one or two) are
installed at specific locations where gas is to be detected, up to 1,500 feet
from the controller. They are electrically connected to the controller via three
conductor cables.
The onboard relays have 10 second on/off time delays to prevent
unnecessary cycling during a fault, warning or alarm condition.
All operator functions are performed from the keypad on the front of the
panel.
Locating the GG-2 Control Panel
The important consideration when installing GG-2 control panel is that it
must be easily accessible for operating personnel.
Installation Guidelines:
Mount controller on a solid surface with minimal vibration. If mounting on a
wall with studs, the mounting screws should be screwed into the studs.
Mount controller thru the holes in the mounting flanges.
Mount controller in a general-purpose location only. Do not install in a
hazardous environment.
Mount controller away from electromagnetic interference.
Protect controller from physical damage.
