GG-6
General Description
The GG-6 is a six-channel control panel designed to accept industry standard
4/20 mA input signals. It provides a regulated 24 VDC power supply to power
all industry standard 4/20 mA gas transmitters, and connected audio/visual
devices. All operator functions are performed from the keypad on the front
of the panel.
The GG-6 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-6 is assembled into a wall mounted enclosure designed for non-
classified locations. The gas sensors are installed at specific locations where
gas is to be detected, up to 1,500 feet from the control panel. They are
electrically connected to the control panel via three conductor cables.
The programmable onboard relays have adjustable on/off time delays to
prevent unnecessary cycling during a fault, warning or alarm condition.
The internal buzzer and horn relay work in unison. Typically the horn relay
should be programmed to be silenceable.
An analog output board (optional) provides an individual 4/20 mA output for
each channel to be monitored by plant PLC or other analog input devices.
Up to three 8-channel expansion modules (GG-XM) can be added on to the
GG-6, expanding the control panel to 30 channels.
A remote display (GG-RD) is also available. A gateway module for network
interface is also available with ethernet and RS-485 ports. Contact Calibration
Technologies for details.
Software versions
Version 2.00 adds time-weighted averaging features to the operating system.
The TWA (8 hour) and STEL (15 minute) functions can be enabled through
the menu, along with their corresponding alarm setpoints and relay output
functions.
Version 3.00 adds a third alarm setpoint and also provides capability
to monitor temperature and pressure sensors with an updated unit of
measurement table.
Version 4.00 adds remote display capability through MODBUS and gateway
module capability.
IMPORTANT: The control panel is shipped with default factory
settings, as listed in the included factory configuration
datasheets. Make sure to program all settings and values in the
configuration menu as intended for your system application.
Refer to the Configuration section of this manual starting on
page 14. Contact Calibration Technologies for further help
configuring your control panel.
