Functie
The Unlock Switch button (WESpT) is used to remove the manual lock that has been placed on a switch. A manual lock prevents a switch from being thrown for any reason.
Bediening
To unlock a switch, WESpT must be pressed together with the button of the switch being manually unlocked. When manually unlocking double or single slip switches, the switch that is unlocked depends on the current switch selection (KWT).
Resultaat
When a switch is manually unlocked, the red manual lock light will extinguish.
Switch Chain Unlocking
To enable the switch chain mechanism, use the WESpT button together with the station button. Notice that the LK light extinguishes. Locking (disabling) the switch chain is done in a similar manner using the WSpT button.
