Torque to Key Material Trapped Key Components Face Plate Optional Box Assembly Fixing Weight Inputs Time Range Description The Electronic Timed-delay Unit (ETU) is used in applications that require an elapsed time to occur before allowing access to a hazardous area. The ETU uses a CU1 control unit timer to execute the timing sequence. Turning a non removable key initiates the timer. When the CU1 times out, its output energizes an internal solenoid, which then allows the removal of either one or two trapped keys. The Single-key Timed delay Unit (STU) has one trapped key. After the CU1 timer has expired, the single trapped key can be removed and used to continue the next sequence in allowing access to the hazard. The single key must be returned to the STU and trapped to allow the non removable key to re-initiate the hazard. The Dual-key Timed delay Unit (DTU) has two trapped keys. After the CU1 timer has expired, both keys can be removed and used to continue the next sequences in allowing access to the hazard. Both keys must be returned to the DTU and trapped to allow the non removable key re-initiate the hazard. See the CU1 control unit for details on setting the delay time.
