Overview
This article describes the available operation modes of the YG80 Weatherproof Lock, including control input behavior, diagnostic testing, failure modes, and heater operation. These modes define how the lock responds to power, control signals, and environmental conditions.
Operation Modes
Normal Mode
The BLUE ‘Control 1’ connection is used to lock and unlock the YG80 by either being connected to the supply voltage or being disconnected. The function of normal mode depends on the current failure mode setting.
When in Fail Safe mode, if power is applied to the BLUE ‘Control 1’ connection, and the YG80 detects the door is closed, the bolt will engage and lock the door. When power is removed, the bolt will disengage and unlock the door.
When in Fail Secure mode, if power is removed from the BLUE ‘Control 1’ connection, and the YG80 detects the door is closed, the bolt will engage and lock the door. When power is applied, the bolt will disengage and unlock the door.
Toggle Mode
The BLUE ‘Control 1’ connection is used to lock and unlock the YG80 by applying a pulse of the supply voltage to toggle the state of the lock. This function does not depend on the failure mode setting.
If a short pulse is applied to the BLUE ‘Control 1’ connection the bolt will disengage and unlock the door. When a second pulse is applied to the BLUE ‘Control 1’ connection, and the YG80 detects the door is closed, the bolt will engage and lock the door.
Twin Wire Mode
The BLUE ‘Control 1’ connection is used to lock the YG80, and the BROWN ‘Control 2’ connection is used to unlock the YG80, by applying a pulse of the supply voltage. This function does not depend on the failure mode setting.
If a short pulse is applied to the BROWN ‘Control 2’ connection the bolt will disengage and unlock the door. When a pulse is then applied to the BLUE ‘Control 1’ connection, and the YG80 detects the door is closed, the bolt will engage and lock the door.
Diagnostic Mode
There are six tests which can be cycled through by toggling the position of the fourth dip switch on or off. The yellow LED will blink based on what test number you are on. Once testing has been completed, ensure all four of the dip switches have been returned to their original operating position.
| TEST | NAME | DESCRIPTION |
|---|---|---|
| 1 | Cycle Count | The green LED lights up if the cycle count is below 300,000 cycles |
| 2 | Motor Health | After 3 test cycles, if the LED goes solid green the motor is in good health |
| 3 | Power Supply | After 10 seconds, if the LED goes solid green the power supply is probably suitable |
| 4 | Control 1 | The green LED lights up whenever the Control 1 input is active |
| 5 | Control 2 | The green LED lights up whenever the Control 2 input is active |
| 6 | Hall Sensor | The green LED lights up whenever the strike magnet is detected |
Failure Modes
Fail Safe Mode
In the event of power failure, when the door is closed and the YG80 is in the locked state, the bolt pin will disengage from the strike. This ensures safe passage in emergency situations, as well as access when power is unavailable.
Fail Secure Mode
In the event of power failure, when the door is closed and the YG80 is in the locked state, the bolt will stay engaged with the strike. If the door is open and the YG80 cannot detect the strike, the bolt will not engage until power returns. This ensures that a lock will not disengage during power failure, keeping the access secured.
Heater Mode (Requires 24VDC Power Supply)
The heater mode allows the YG80 to be used in colder climates, where the bolt pin can become iced over. When the heater mode is enabled, the YG80 will automatically activate the heater to ensure the lock is operating above freezing conditions. The heater will self-regulate and only be active when it is needed to conserve energy. Refer to Section 2 for information about the use of the neoprene gasket for added benefits in colder climates.
