The SBC1102 spray booth controller, available from Ptronik formerly P Thomas Electronics , will control and operate the fan and air solenoid in spray booth.
In the spray booth controller, the user presses the START button to energise the exhaust fan, and within 10 seconds the air flow switch closes to indicate the correct air flow. The pre-purge time is set to 1 minute after which the solenoids will energise to allow the spray gun to operate. The user can push the STOP button to switch the system off. The solenoid de-energises and stops the air flow to the spray gun. The fan will operate for a post purge time of 5 minutes and then stop.
During the post-purge time the air solenoid can be energised at any time by pressing the start button. If the exhaust air fails during operation, the flow switch contact opens, and the solenoid will de-energise and stop the operation of the air gun. The no air flow indicator will illuminate and the alarm contact will close. The SBC-1102 comes with plug-in base in an ABS enclosure.
