| Description |
| The D Lock is a two part access interlock comprising of a main body and catch. The catch is available in two options, one suited to well aligned doors, the other suited to poor, mis-aligned doors. The interlock is manufactured in brass and comes with the bras s figure or Q type lock portions. The lock is ideally suited for use on light duty panel doors in dry, non-corrosive environments where the lock is subject to light to medium use. Typical indus tries using the D Lock are Control Panel Builders , HV and LV Switchgear and the food industry. |
| Operation |
| Under normal operating conditions the key is free and the catch is trapped in the lock. The catch can only be released when the key has been inserted and turned. With the catch removed, the key is trapped within the lock. Please contact Castell for the alternative key / catch conditions that are available. |
| Typical System |
| The D Lock is designed to operate as part of an integrated safety system, controlling access to hazardous areas . A typical example of isolation and access control is shown below. |
 |
| System Description |
| The removal of the isolation key in the KSS20, isolates the electrical supply to the LV Panel. This key is then used to unlock the D interlock on the panel door. The door can only be opened when the electrical supply has been switched into a safe condition. |
