BRONKHORST HIGH-TECH B.V.

Potmeters for controller parameter setting are accessible via holes in the rear panel.

Potmeter:

P6: controls the valve quick start-up voltage. Set for optimum fast response behaviour from zero

setpoint. (optional)

P3: (flow control only) Controls the output differentiating network. This determines the dynamic

response characteristic of the system.

P4: (flow control only) Controls the D-action of the control circuit.

3.2 Connection to measuring devices

The instrument connector is a female sub-miniature 9-pin D-connector. The pin designation is according to the

Bronkhorst High-Tech B.V. standard for intrinsic safe instruments
