RemoteTransducer lnput
(Factory lnstalled Option)
Refer to Figures 3-3, 3-4 and 3-5. To allow the Model 5965/5851EM control
circuitry and valve to be used with an 0-5 Vdc external transducer signal, a
green jumper is moved to the lower two pins at J7. With this feature
enabled a 0-5 Vdc signal may be applied to the external transducer input
terminal. The Model 5965/5851EM controller circuitry will modulate the
valve position to increase or decrease the flow rate to maintain the
transducer output at the desired set point. The control circuitry is reverse
acting, e.g., for an increase in transducer output the flow will
correspondingly be decreased.
Configuring PC Board (Current l/O Option)
Setpoint (Command) lnput
The mass flow controller can be configured for voltage or current setpoint
(command) input. Jumper J7 (green) must be in the right-hand position for
0-5 Vdc setpoint and in the left-hand position for a 4-20 mAdc setpoint
input.
SignalOutput
A 0-5 vdc flow signal output is always avaílable. The current signal output
is jumper selectable for either 0-20 mAdc or 4-20 mAdc. Jumpers JB and
J4 (blue) must be in the upper position for 0-20 mAdc output and in the
lower position for 4,20 mAdc output.
Note: Both J3 and J4 must be in the same position. Jumpers J3 and J4 do
not affect the voltage output.
Soft Start
To enable soft start, place Jumper J2 (red) in the right-hand position (ss).
To disable soft start, place Jumper J2 in the left-hand position (N).
