CAUTION –
This device may be connected to multiple power
sources (mains power and internal battery) and may start
unexpectedly unless both power sources are disconnected .
Removable terminal blocks facilitate
ease of field wiring and testing.To
remove a terminal block from the PCB
receiver, pull straight OUT in a direction
parallel to the PCB. Use caution
when reinserting block - make sure
all pins are aligned before seating.
Torque Switch (TS) equipped
products have a secondary set
of cams/switches to protect the
actuator, equipment and processes.
CCW
CW
Note that the rotation seen from below is a
mirror of the direction viewed from above.
1 . The battery system should remain UNPLUGGED until AFTER the actuator
has been mounted and tested for proper travel and end stop calibration .
• The battery system will be connected during the Commissioning Procedure .
1 . Fully CLOSE the valve or damper to which the actuator is to be mounted .
2 . Assemble necessary linkage hardware and attach the actuator to the valve
or damper .
3 . Center the actuator on the valve or damper drive shaft and tighten all hardware .
4 . Before applying power to the unit
, rotate the manual override handwheel
from the fully CW to the fully CCW position to check for unobstructed manual
operation of the valve or damper .
5 . HRSN4 Series actuators utilize a removable terminal block to simplify field
wiring and testing .
• To remove a terminal block from the PCB receiver, pull straight out in a
direction parallel to the PCB .
• In the photo at right, the RIGHT side of either terminal block (between the
PCB mounting screws) is pulled out to the RIGHT .
• After wiring, reinsert the terminal strip into the receiver .
This is a keyed pair and can only be inserted one way .
• Screw terminals are rated to accept 14AWG down to 18AWG solid or
stranded wire .
TERMINAL NUMBERING HAS #1 AT THE BOTTOM .
6 . Refer to your product part number to determine which wiring diagram to
follow when wiring up the actuator .
CAUTION –
Be sure to make field connections to the proper terminal
as identified by the LABEL and not the position!
Notice:
Torque switches are factory set and are not adjustable.
7 . Note that although terminals are labeled as 1-8 and A-D, not all terminals are
used on all models .
8 . Make the electrical connections per the appropriate Wiring Diagram for
your actuator .
9 . Connect POWER and CONTROL to the correct terminals .
10 . Terminals A~D on each actuator are for the (adjustable) auxiliary switches .
These are dry type (volt free) Form A contacts rated 10A @ 250VAC Max .
11 . Select actuators covered in this manual are equipped with torque switches
which protect the actuator motor and gear train . Torque switches protect
controlled valves or actuators from damage in the event of a high torque
condition . More information can be found throughout this manual .
Notice:
All HRSN4 Series actuators rotate CW to close the output shaft
out the bottom of the actuator
when viewed from above.
On all HRSN4
models, the cam shaft and the indicator rotate CW to close as well .
