Valve mounting
A.
Mounting is most easily done with the valve shaft pointing vertically upward, but the actuator may be
mounted in any position.
CR50S actuators are supplied with a female drive output.
The bottom bolt pattern is drilled as F03, F05 & F07 according to ISO5211.
It is mandatory that the actuator be firmly secured to a sturdy mounting bracket or directly mounted to
the valves ISO mounting pad. High tensile bolts or studs with spring locking washers must be used.
The valve output stem must be in line with the actuator output drive to avoid side loading of the stem.
To prevent backlash, no flexibility in the mounting bracket arrangement should be present.
Wiring
B.
Precaution
a.
Cable entries are machined with PF 1/2 and sealed by plug before delivery.
(1)
Please remain the plug as it is if user doesn't use both cable entries.
(2)
Please make sure to seal the entries by using rubber or metallic packing after wiring,
(3)
so that water or other foreign material may not come in.
If suitable cable connection is not used for wiring, factory won't guaranty the performance.
(4)
Electrical wiring
b.
Check if the electrical specification like as power, wiring or etc are correct.

Wiring diagram is to be supplied together with the actuator.
(2)
Do the wiring as per the given wiring diagram, such as power, control power, internal wiring and
(3)
ground.
Make sure to supply the electric power to the heater to keep inside of the actuator clean and
(4)
dry for anti-condensation.

(5)
Make sure that one relay operates one actuator only (Can't operate two or more actuators).
(6)
Make sure to clean inside of the actuator and no foreign material inside.
(7)
After the testing, check that all cable glands are correctly tightened.
(8)
Applicable cable glands should be selected to meet the application's condition.
It is recommended to use the grade of IP67 cable gland.
Make sure all incoming power is disconnected before wiring!!!
How to connect
c.
"Pluggable connection system" terminal block is installed for saving
time of wiring job and it is make the wiring job easy or simple
Remove cable plug and open cover of chamber of terminal block
(1)
Disassemble female connector from terminal block
(2)
