The PL2 Control Panel Board is being used in conjunction with the PA-Air Pilot to regulate steam pressure. A small air regulator on the panel board can be adjusted to control the air pressure to the pilot. One gauge on the panel board measures air line pressure to the panel board and the other gauge shows the air pressure being sent to the pilot. Steam pressure at the outlet of the regulator is controlled by the air pressure signal to the pilot. Depending on the air pilot model chosen (PA1, PA4, PA6), there will be a 1:1, 4:1, or 6:1 ratio of outlet steam pressure to air pressure.
Description of Operation
The PL2 Control Panel Board is being used in conjunction with the PA-Air Pilot to regulate steam pressure. A small air regulator on the panel
board can be adjusted to control the air pressure to the pilot. One
gauge on the panel board measures air line pressure to the panel board
and the other gauge shows the air pressure being sent to the pilot.
Steam pressure at the outlet of the regulator is controlled by the air
pressure signal to the pilot. Depending on the air pilot model chosen
(PA1, PA4, PA6), there will be a 1:1, 4:1, or 6:1 ratio of outlet steam
pressure to air pressure.
