DE100 and DE200 drive carriers are locked into place with an operator key lock pawl. Removal of the carrier while the drive motor is still running can cause possible damage to the drive and possibly the drive carrier. An available option for the DE100 and DE200 is a factory installed solenoid bar lock, designed to prevent removal of the drive carrier from the receiving frame for an installer/integrator preset period of time. The device spin-down time that is allocated is user-selectable from 15-45 seconds. The user can access the solenoid timing control via a small timing switch located on the side of the DE100 receiving frame. This timer is preset at the factory to 20 seconds, which is a nominal drive manufacture spin-down time period. Higher performance drives may require longer spin down times.
