Err3 [Left Display}
Reason:
On Power Up, the Switchover checks the switchover pressure value to determine if it is set higher
than the cylinder type selected on the left side. If it is, it is considered an invalid condition.
Example: Switchover pressure set to 300 PSI and the cylinder selected is 230 PSI .
Solution:
This problem will most likely occur when using liquid cylinders.
To solve this problem you must first determine if the problem is the cylinder size selected or the
switchover pressure setting. The switchover pressure MUST be lower than the cylinder size selected.
If the switchover pressure is set incorrectly (lower than the cylinder size) it must be increased. Turn
power OFF to the system. Open the door and locate the switches at the bottom of the electronic
circuit board. Referring to the Section “Setting Switchover Pressure” in this manual set the
switchover pressure to a value above the cylinder size. Close door and turn power ON.
If the cylinder selection is incorrect turn power OFF to the system. Open the door and locate the
switches at the bottom of the electronic circuit board. Referring to the Section “Setting Switchover
Pressure” in this manual set the switchover pressure to 0 PSI. Turn power back ON and select the
correct cylinder size by pressing the left source select pushbutton.
Turn Power OFF again and open the door and set the switchover pressure to the appropriate value.
Close door and turn power ON. System should operate properly.
