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.
