Type of duty according to VDE 0530 / IEC 60034-1
Short
–
time duty S2
Intermittent duty S4
The operation time at a constant load is
short, so that thermal equilibrium is not
reached. The pause is long enough for the
machine to cool down to ambient tempera-
ture. The duration of the short –time opera-
tion is limited to 15min (10min, 30min)
The duty is a sequence of identical cycles which
consist of starting time, operation time with con-
stant load and rest period. The rest period allows
the machine to cool down so that thermal equilibri-
um is not reached. The relative on-time at S4-25%
or S4-50% is limited to 25% and 50% respectively.
3.1.5. Space Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The heat-
er integrated in the control unit prevents from this in general.

3.1.6. Hand wheel and Declutching
HQ actuators are provided a declutchable manual override system.
① In order to manually operate the actuator, pull the manual override
engagement lever towards the hand wheel until it remains in position.
② Turn the handwheel until the valve reaches the required position
③ Turn clockwise to close and counter-clockwise to open
Note ;
The override engagement lever returns automatically to auto
position when the actuator is operated electrically.
3.1.7. Lubrication
HQ is a totally enclosed unit with a permanently lubricated gear train (Moly EP Grease). Once installed
lubrication should not be required. However, periodic preventative maintenance will extend the operat-
ing life of the actuator.

Danger: Installation, commissioning, maintenance, repairs and modification work must only
be performed by qualified personnel with extensive knowledge on how to work on explo-
sion-proof electrical equipment.
Note :
1) Further information should be used of the HQ electric actuator catalogue.
Refer to the Cl.2.2 Initial inspection of this manual.
Warning :
Read this installation and maintenance manual carefully and completely before attempting to in-
stall, operate, or troubleshoot the HKC actuator.
4.2. Actuator Mounting
Note : Prior to mounting the part-turn actuator must be checked for any damage.
Damaged parts must be replaced by original spare parts.
4.2.1. Mounting is most easily done with the valve shaft pointing vertically upward. But mounting is also
possible in any other position; the actuator may be mounted in any position.
4.2.2. The HQ-series electric actuators are supplied with a female drive output. The ISO5211 bolt patterns
are provided for actuator mounting. The actuator drive bush is removable for ease of machining. It
is mandatory for the actuator to be firmly secured to a sturdy mounting bracket or directly mount-
ed to the valves’ ISO mounting pad. High tensile bolts or studs with spring locking washers must be
used.
4.2.3. The valve output shaft must be in lined with the actuator output drive to avoid side-loading the
shaft. To avoid backlash, flexibility in the mounting bracket or mounting should not be allowed.
CAUTION:
Do not attempt to work on your HKC actuator without first shutting off the incoming
power.
Do not attach ropes or hooks to the hand wheel for the purpose of lifting by hoist

4.4. Torque Switch Setting
4.4.1. Torque spring, which detects the variation of torque during the operation, is installed to prevent
damaging the valve and actuator under overload condition. Once the actuator is under overload,
the torque switch trips, and the actuator stops immediately.
4.4.2. The torque switches are set by manufacturer on the production site. If re-setting is necessary, please
contact the HKC service representative before setting the torque switch.
CAUTION: Do not reset torque switch to a setting higher than the maximum setting stated by
the manufacturer.
4.5. Counter-Clockwise to Close Setting
Standard actuators are normally set to clockwise rotation to close. However, the rotation can be reversed
to counter-clockwise to close by simply reconfiguring the wiring as follows:
4.5.1. Reverse wiring in the main terminal block: 9 & 10 as well as 11 & 12.
4.5.2. Adjust the visual indicator to suit the counter-clockwise rotation.
If a PCU card is installed, [please refer to DHC-100 for ac or DMC-102A for dc PCU manual of Peak-
tronics Co. --- 17 rev1]
4.6. Mechanical Travel Stop Adjustment
4.6.1. Loosen both (open and close) travel stopper bolt nuts by 3-4 threads.
4.6.2. By turning the hand wheel, manually operate the actuator so that it is in close position until it
makes a contact with the closed limit switch.
4.6.3. Tighten the close travel stopper bolt until it contacts the 2nd worm wheel (in this position the close
travel stopper bolt should not be able to travel any further).
4.6.4. Loosen back the close travel stopper bolt by on turn and tighten the close travel stopper bolt nut.
4.6.5. Repeat the same operation for setting of the open travel stopper bolt.
4.7. Setting potentiometer (Replacing and setting)
The potentiometer has been calibrated at factory. However, if re-calibration is required, proceed as fol-
lows:
4.7.1. Manually rotate the hand wheel of the actuator to fully closed position.
4.7.2. While measuring the resistance between P1 (orange) and P2 (grey), gently rotate the Potentiometer
Gear until it reaches between 80 - 120 Ω (100 Ω preferred).
4.7.3. Engage the Potentiometer Gear into the Point Shaft Gear and use an L-wrench to tighten the screw.

4.10. [AC/DC Multi-Board
4.10.1. General
① ACDM-200 series is an electronic motor converting module that can operate an actuator by 12 V
dc or 24 V dc motor with 12 V ac or 24 V ac capacitor starting type or split phase type motors.
② The converter module can operate 12 V dc or 24 V dc motor actuator just like an ac motor actua-
tor. One of characteristic of the converter module is a dynamic brake function. This function im-
proves precision by electrically braking without mechanical braking on valves due to slip by inertia.
