FAQ / The transaction viewer reports a lot of time-outs on specific terminals.

It is possible that you do not have sufficient power to the unit or the current is not sufficient. This occurs when a strike lock or mag lock is connected to the same power source and when a relay is activated, the lock draws too much current thus resetting the unit.

It is also possible that you do not have back EMF protection (MOVs) installed on the locks and the units are being reset. Refer to the hardware manuals for instructions on installing back EMF protection.

Another possibility is that certain sites where transmission lines are long or multiple star formations are used, may experience “time-outs” on certain Amano controllers or terminals. These are caused by reflections on the RS485 lines. To solve the problem it may be necessary to terminate the lines.  It is always best to contact support at 800-390-5837 before trying this option.
