lever.
NOTE: Place cover over PIBV2 to ensure that actuating lever
does not interfere with cover. If actuating lever interferes with
cover, remove lever and break off additional length at breakaway
point. Refer to Figure 7.
8. Open the valve to the full open position and tighten screw
to hold actuating arm in position. (Actuating arm length will
adjust slightly as valve is opened.) Check to ensure that in
the full open position the actuating arm is not resting on the
nipple. Do this by depressing the actuating cam to further
stretch the spring, ensuring that more travel is available when
the valve is open. If there is no travel, damage may occur to
PIBV2A actuating arm. Some slight alteration of the valve
stop setting may be necessary to ensure that no damage
occurs.
9. Carefully close valve and note the number of handle revolu-
tions until the switch trips. The switch must trip within
1
⁄
5
of
the total travel range of the valve.

visory switch models. When grounding is required, clamp
wire with the screw in hole located near conduit entrance.

Section 4
Reversing The Action Of PIBV2A
1. Loosen the 3 phillips screws on the top of the black switch
enclosure so that the switch enclosure is loose and free to
move (see Figure 5).
2. Slide the switch enclosure away from the conduit entry
toward the actuating pivot arm as far as possible and tight-
en the 3 screws to secure the enclosure. (Ensure that switch
enclosure remains oriented away from the conduit entry as
screws are tightened.)
3. Grasp the spring at the center and lift it over the actuating cam
so that it seats on the opposite side of the actuator (see Figure
5).
