Doorlock Unlock Delay Unit (A31)
The Door Unlock Delay Unit (A31) will unlock the
machine approximately 3 minutes after disconnecting
power. A31 has two onboard capacitors that are
charged via the A31's direct connection to L1 and N.
When power is disconnected from the machine an
onboard timer activates. After 180 seconds, the time it
required for a full load at maximum extract to come to
a stop, the onboard relay discharges the capacitor to
the unlock coil on the Doorlock (A111) allowing the
door to be opened. Care should be used when opening
the door after disconnecting power, as water could spill
from the machine.
If the machine is unattended in the event of a power

failure lasting longer than approximately 3 minutes

door and continue the cycle.
The A31 has a connectorized harness with 12 VDC,
250 ma available for optional payment systems.
