Alarm Output Connections
The GF-A2100/GF-A2200 provides an alarm output that can be configured as relay dry contacts, or as direct drive (15
mA typical) for an external LED alarm indicator. The alarm output interface is set using the LED PWR jumper on the main
circuit board as shown in Figure 9. With the LED PWR jumper on, the alarm output is set to provide an external LED drive
(15 mA typical) at terminal 4, with ground return at terminal 6. With the LED PWR jumper OFF, the alarm output is set
to provide relay dry contacts between terminals 4 and 5 (contacts rated at 30VDC/24VAC 3 amps maximum). The Alarm
can be set as contacts close or contacts open on alarm as detailed in the Transmitter Setup menu later in this manual.
For external LED drive alarm output, ensure that the LED PWR jumper is installed, and connect the LED anode (+)
to terminal 4, and cathode (-) at terminal 6.
OR
For relay dry contact alarm output, ensure that the LED PWR jumper is removed, and connect the alarm wires to
terminals 4 and 5. Contact rating is 30VDC/24VAC 3 amps maximum.
Sensor Probe Connection
With 24VAC power OFF, connect each sensor probe cable plug to the transmitter by pushing it into the keyed cir-
cular receptacle (shown below) located at the bottom of the transmitter enclosure. Do not twist the connector.
Sensor probe cable plugs are “keyed”. Line up the connector plug with the transmitter receptacle and push straight on. DO NOT
TWIST. Squeeze cable plug “ribs” towards receptacle when removing. Forcing the cable plug in or out of the receptacle will dam-
age the connectors and void warranty.
Sensor probe must be connected to the transmitter before application of 24VAC power in order to properly “flash” sensor calibra-
tion data to the transmitter.
Initial Power Up
Upon application of 24VAC power, the GF-A2100/GF-A2200 will initiate a brief self-test, indicated by dashed lines on the
LCD, and then will automatically engage the Start Up Menu to prompt the user through menus that configure the trans-
mitter for the specific installation/application. The Start Up menu will also be engaged each time power is applied and
the required area for any of the connected probes has not been set (*AR1(and/or AR2)=0.00 SQF). Refer to the Start
Up Menu and Set Up menu details and descriptions later in this manual for a complete description of programming
options and features.
Operating Modes
The GF-A2100/GF-A2200 provides two independent 12-bit (4096 discrete states) linear analog outputs. Each output
can be independently enabled, disabled and configured within the Set Up Menu as follows:
Set as Standard flow or Temperature output from Flow 1 (and Flow 2) probes.
Set as a PID Control output signal (with advanced PID control options available)
Set as an airflow alarm status output (to indicate Hi limit, Low limit or Deadband with hysteresis conditions)
Set as a temperature alarm output (to indicate Hi limit, Low limit or Deadband with hysteresis conditions)
Set as Differential flow output to indicate the difference between Flow 1 and Flow 2 probes (GF-A2200 only)
In addition, the text displayed for each output on the GF-A2100/GF-A2200 LCD display panel can be renamed to suit your
specific requirements (5 characters max). Analog outputs are field selectable for 0-10VDC, 0-5VDC or 2-10VDC to per-
mit simple integration with virtually all building automation systems. Refer to the Set up menu details and descriptions
later in this manual for a complete description of analog output and PID control output options.
