Pressure Regulator Temperature Control

DANGER
Electric
Shock Risk
The heated pressure regulator contains an adjustment for the temperature control
set-point (factory-set to approximately +24ºC (+75°F)). It may need adjustment to
increase/decrease the heat requirements to the regulator dependent on the high/low
inlet gas pressure.
To make an adjustment proceed as follows:
1. Unscrew and remove the cover of the junction box after fi rst loosening
the hex grub screw.
2. Adjust the heater output by turning the potentiometer - clockwise to
increase and anti-clockwise to decrease.
3. The seven markings around the potentiometer equate to an approximate
temperature value for the heater of:
1 = +24ºC (+75°F)
2 = +27ºC (+80°F)
3 = +29ºC (+85°F)
4 = +35ºC (+95°F)
5 = +43ºC (+110°F) May be advised by Michell dependent upon application
6 = +54ºC (+130°F) Should not be set
7 = +79ºC (+175°F) Should not be set
4. Replace the junction box cover and tighten the hex grub screw.

This operation will expose electrical parts operating at high
voltage. Therefore, power must be isolated from the supply for
the Sampling System before making adjustments.
