Err5
Reason:
a. The Toggle switches enabling the Left and Right Delivery Regulators are both OFF.
b. Both the Left and Right Delivery Regulators have failed (not likely).
c. The system was powered up with no inlet pressure on either side.
Solution:
a. In a normal service situation when a Delivery Regulator is removed from the system the
procedure requires that the toggle switch on the inside panel near that regulator be turned
OFF. This tells the control electronics that it is no longer available for use. When the
Delivery Regulator is replaced this toggle switch must be turned back ON in order for the
control electronics to know it is available again. Make sure the toggle switches are in the
correct position.
b. When a delivery regulator can no longer maintain the set outlet pressure the system will
switch to the other delivery regulator to try to maintain the outlet pressure. In this scenario
there is no inlet pressure to feed the delivery regulators and the system will report this error.
It is actually a false error because neither delivery regulator has failed.
Power the system
OFF and restore the inlet pressure. Power the system back ON. It will enter Calibrate
mode.
Refer to the section in this manual titled “Setting Delivery Regulator Pressure”.
c. A more serious situation would be that both delivery regulators have actually failed. This
requires replacement of both regulators for the system to work properly. This type of failure
would generally be unlikely but in the event that it has occurred, the delivery regulators must
be replaced.
Err6
Reason:
An attempt is being made to select the right side delivery regulator when it is not available.
Solution:
Replace the right side delivery regulator and place it back into service.
