Operating Configuration

The operating configuration of the IEGL controls how the lock will function and there are several settings available. There are four dip
switches on the printed circuit board with three being used to configure the lock and the fourth for diagnostic purposes. The dip switches
are located on the top of the printed circuit board and can be set as per the following table.

1. Fail State - Switch 1
The fail state of the IEGL is determined by the selection of switch 1; however there is an additional state that can be used if desired. With no
batteries installed the lock will default to Fail Maintained. In this configuration and in the event of a power failure, the lock will stay in the position
it was in before the power was removed. With the batteries fitted however, selecting Fail Safe or Fail Secure ensures that the IEGL will move to the
selected state if the power does fail.
2. Auto re-lock - Switch 2
It is recommended that Auto re-lock be ON in most installations. The ability of the IEGL to sense the gates position and automatically lock when
it is closed is paramount to increasing security as it eliminates the need for the user to do so. If Auto re-lock is not selected the IEGL operates on a
toggle method. In this configuration an activation of the control signal will cause the IEGL to unlock and a second activation will cause it to lock.
3. Timed re-lock - Switch 3
Timed re-lock can only be enabled when Auto re-lock has been selected. It is recommended that Timed re-lock be ON in most installations. For
increased security the IEGL has the ability to automatically lock itself after a timed period in the event of a user failing to do so. If an unlock signal
is given to the lock, but the gate is not opened, the IEGL can automatically lock itself again after one minute. This ensures that a gate can not be
left unsecured if it has been unlocked but not opened.
4. Diagnostic mode - Switch 4
By default the Diagnostic mode should be set to OFF. If the IEGL fails then the Diagnostic mode can be activated and information extracted
from it to help determine what has caused the fault. This information needs to be interpreted by ASSA ABLOY New Zealand Ltd.

Operation

The operating scenarios detailed overleaf stay the same regardless of whether the IEGL is configured in a Fail Safe, Fail Secure or Fail
Maintained state. The state of the lock is only relevant in the event of a total power failure.
Both scenarios assume that the control signal is open at the start of the operation sequence as a maintained connection will cause the lock
to stay unlocked indefinitely.
