GF 9950-10 Six Channel Transmitter
Example: Set a relay R1 to
turn on at a low setpoint of
5.5 gpm with a time delay of
15 seconds and turn off at
8.0 gpm.
Remember,
SET LOW + hysteresis = OFF
Relay 1 Source = CH1 Primary
Relay 1 Mode = Low
R1 Set Low = 5.5
R1 Hysteresis = 2.50
R1 on delay = 15.0 sec
Fail-Safe Behavior
No matter the setting, the Open Collector output turns off if the 9950 looses power. This must be taken into account when
evaluating system failure consequences. If the system layout requires a "closed" or "on" condition for the output in case of power
loss, a mechanical dry-contact relay (NC contacts) must be used instead of the Open Collector (R1) output.
Set your relay functions to your own application requirements.

Relay Functions
When connecting a non-GF sensor to the 9950, the sensor’s 4 to 20 mA signal must be
converted to Digital (S
3
L). The 8058 i-Go Signal Converter accepts any 4 to 20 mA signal
and converts it into Digital (S
3
L).
1. Wire the 8058 between the 4 to 20 mA loop source and the 9950 Digital (S
3
L) input
terminals.
2. In the 9950 INPUT menu, sensor TYPE screen, select the '4 to 20 INPUT' sensor
(Refer to System Setup Menu, page 11).
