RESETTING DELIVERY REGULATOR PRESSURE TOLERANCE (REPAIR)
The range of allowable variation in delivery regulator pressure is settable. The factory default is +/- 7 PSI. This value may be
changed by setting DIP switches on the Electronic Control Board or remotely via the optional serial interface. To change this pressure
tolerance, perform the following steps:
1.
Turn AC power OFF to the system.
2.
Open door by loosening the four screws holding it to the cabinet.
3.
Using Figure 10, locate DIP switch SW6 at the bottom of the electronic circuit board on the door.
Figure 10
4.
Using Table 5 set the pressure range tolerance.
Note: It is highly recommended that the tolerance setting be no less than 5 PSI for proper system operation.
5.
Close system door and tighten 4 screws holding door to cabinet.
6.
Turn AC power back ON. The new tolerance will take effect on power ON.
