Page 8: Gf-1200-A Installation
Installation of the GF-1200-A consists first of installing the sensor probe, then installing the transmitter, and last, installing the power and analog signal wiring to the airflow station. The following paragraphs detail each of the individ- ual procedures required for installation of the GF-1200-A. Convenient check boxes are included to ensure that each step is completed. - Page 9 Figure 4 4 .

Page 10: Gf-1200-A Transmitter Installation
GF-1 1 200-A A T T RANSMITTER I I NSTALLATION The GF-1200-A transmitter is designed for use in an environment between -20° F to 120° F (-28.8° C to 48.8° C) where it will not be exposed to rain or snow. In locations where precipitation may be encountered, a NEMA-4 enclosure must be provided to enclose the GF-1200-A transmitter. -
Page 11: Gf-1200-A Transmitter Wiring
Transmitter wiring consists of connecting the 24VAC input power, the analog output signal wires and optional alarm out- put wires at the GF-1200-A. Refer to Figures 6 and 7 for additional detail. Following installation, the airflow measure- ment station is ready for operation. Custom setup options (other than the default values) can be entered as outlined in the transmitter Setup Procedure. -
Page 12: Alarm Output Connections
Alarm O O utput C C onnections The GF-1200-A provides an alarm output that can be configured as relay dry contacts, or as direct drive (15 mA typical) for an external LED indicator. The alarm output type is set using the LED PWR jumper on the GF-1200-A circuit board as shown in Figure 6. - Page 13 TRANSFORMER OUTPUT, ALL GND CONNECTIONS MUST BE COMMON TO PREVENT DAMAGE, OR AN ISOLATION TRANSFORMER MAY BE USED. 3. ALL DEVICES ON MULTIPLE GF-1200-A TRANSMITTER INSTALLATIONS WITH A COMMON 24VAC SOURCE MUST BE WIRED IN-PHASE TO THE SAME TERMINALS (e.g.: PIN 6 to PIN 6, PIN 7 to PIN 7).

Page 14: Gf-1200-A Alarm Options And Description
Setup menu as an airflow alarm or system trouble alarm. The alarm output type, either exter- nal LED driver (15 mA typical), or relay dry contacts, is determined by the LED PWR jumper on the GF-1200-A transmit- ter circuit board (Figure 6). -
Page 15: Converting The Analog Output Volumetric Flow To Airflow Velocity
A test output signal between 0 and 100% of the selected full scale output (0-10 VDC, 0-5VDC or 2-10 VDC) can be pro- vided by the GF-1200-A to verify proper conversion of the output signals from the transmitter at the host control system. -

Page 22: Field Adjustments
1200-A airflow station is installed. The inherent accuracy of the field reference measurement will not be better than ±5% of reading and measurement uncertainty can often exceed ±10%. Do not adjust the output of the GF-1200-A if the dif- ference between the transmitter and the field reference measurement is less than 10%. - Page 23 Figure 1 1 2.
