Lock Horizontal Operating Handles in the OFF/O Position
Some units use a horizontal operating handle. The horizontal operating handle
can be locked in the OFF/O position by putting the shackle of the lock through
the open slotted area to the left of the operator handle.
Figure 32 - Locking a Horizontally Mounted Operating Handle in OFF/O Position
Lock Units with Operating Handles in the ON/I Position
Follow this procedure to lock the operator handle in the ON/I position.
1.
Drill out the hole to 3/8 in. (9.5 mm) diameter maximum.
2.
Insert the shackle of the lock.
The following instructions assume that the handle is in the ON/I position:
•
For units with small handles, the hole is in the upper portion of the
operator handle assembly.
•
For units with medium and large operator handles, the hole is underneath
the operator handle on the handle assembly.
•
For units with a horizontally mounted handle, the hole is on the left-hand
side of the handle assembly.
ATTENTION:
Locking an operating handle in the ON/I position may be in
conflict with local codes and emergency shut down requirements.
