See Test Mechanical Device Operation on page 12 as needed.**
Excessive tamper (while power applied, the pushpad was pulled out
at least 3 time)
Wait 15 seconds and latchbolt will retract again OR remove and
reapply power to clear condition
Voltage low during latchbolt retraction (latchbolt retracts at reduced
force)
Wire length is too long, wire gauge is too small or power supply has
poor regulation
Input voltage is too high for proper operation
Wrong power supply, power supply defective.
Input voltage is too low for proper operation
Wrong power supply, power supply defective or not set to the proper
output voltage.
To set, remove AC power from power supply, change power supply
