1. Single Acting/Spring Return (Plug Outlet Port 2) increasing signal causes pressure to
increase in Outlet Port 1.
2. Double Acting/Double Return (Pipe Outlet Port 2 to drive actuator towards the desired
failure direction) increasing signal cause pressure to decrease in Outlet Port 2 and
pressure to increase in Outlet Port 1.
On loss of electrical power Outlet Port 1 has zero pressure and Outlet Port 2 has full
pressure.
5.6 SPECIAL NOTE Flow Capacity
ICoT 5500
standard flow design is suitable for actuator swept volumes of a minimum 40
inch
3
(0.65 liters) to a maximum of 600 inch
3
(9.80 liters) for proper Auto Calibration
functionality. It should also be noted that this is to be used as a general guideline only. The
actuator/ valve package dynamics would dictate the success of the Auto calibration routine
and could be compromised by the following: instrument air supply, volume capacity,
actuator sizing, tubing size and actuator/valve health.
ICoT 5500
Optional High Flow design is suitable for actuator swept volumes of a minimum
200 inch
3
(3.2 liters) to a maximum of 1000 inch
3
(16.30 liters) for proper Auto Calibration
functionality. It should also be noted that this is to be used as a general guideline only. The
actuator/ valve package dynamics would dictate the success of the Auto calibration routine
and could be compromised by the following: instrument air supply volume capacity,
actuator sizing, tubing size and actuator/valve health.
5.7 Setting of switches on a rotary ICoT
1. Operate the actuator to the desired extreme.
2. Loosen magnetic trigger bolt #1. (See Figure 5-10)
3. Slide trigger bolt #1 beneath the first switch and tighten with wrench.
4. Operate the actuator to the opposite extreme.
5. Loosen magnetic trigger bolt #2.
6. Slide trigger bolt #2 beneath the second switch and tighten with wrench.
