Prosafe Trapped Key Interlock Switches
Solenoid Release Units
Description
The solenoid release unit is used for electrical isolation of machinery
to enable safe access. It consists of a rotary power switch (RPS) and
a solenoid. The trapped key can be removed once an external signal
is given to its internal solenoid locking mechanism. An indicator
light on the SRU indicates when trapped key can be removed; that is,
when power is applied to the solenoid. The solenoid signal only
needs to be present when key removal is necessary. The solenoid is
rated for 100% duty cycle. Power to the solenoid can be removed
after the trapped key is removed.
Removing the trapped key causes the isolating power switch to
change state; the normally open contacts open and the normally
closed contacts (if applicable) will close.
The trapped key can then be used in the next sequence of the
operation.
