3.1.4 Duty cycle
Duty cycle rated IEC60034 – S4 50% / S2 30 min
Exceeding the actuator’s rated duty cycle may cause thermal overload.
NOTE: 1)TYPE OF DUTY ACCORDING TO VDE 0530 / IEC 60034-1
3.1.5 Heater
Condensation in the actuator is possible due to wide fluctuation of the ambient temperature. The heater integrated in the control unit prevents this in
general.
3.1.6 Manual override
5630-006 actuators are provided with a manual system. The standard 5630-006 actuators come with a manual override hand wheel. This hand wheel
is located at the bottom of the unit and can be easily operated with a Hex wrench. Turn the hand wheel until the valve reaches the required position (turn
clockwise to fully open and counter-clockwise to fully close).
Caution! here must be no voltage while turning the actuator.
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 temperature. The duration of
the short –time operation is limited to 15min (10min, 30min)
The duty is a sequence of identical cycles which consist of
starting time, operation time with constant load and rest period.
The rest period allows the machine to cool down so that ther-
mal equilibrium is not reached. The relative on-time at S4-25%
or S4-50% is limited to 25% and 50% respectively.
3.1.7 Lubrication
5630-006 electric actuator is a totally enclosed unit with permanent lubricated gear train (Moly EP Grease). Once installed, further lubrication should not
be required. However, periodic preventative maintenance will extend the operating life of the actuator.

4. INSTALLATION
4.1 Pre-installation for using in general service
Verify the actuator’s nameplate to ensure correct model number, torque output, operating speed, voltage and enclosure type before installation or use. It
is important to verify that the torque output of the actuator is appropriate for the torque requirements of the valve, and that the duty cycle of the actuator
is appropriate for the intended application.
WARNING:
Read this installation, operation and maintenance manual carefully and completely before attempting to install, operate, or troubleshoot the
5630-006 actuator.
4.2 Actuator mounting
NOTE: Prior to mounting, the actuator must be checked for any damage. Damaged parts must be replaced by original spare parts.
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. The 5630-006 series actuators are supplied with Union joints & nuts, the Union joints are removable for the ease of assembly.
CAUTION: Do not attempt to work on your actuator without first shutting off the incoming power

This function is used for automatic setting of the PCU card to the predefined limits.
While the actuator is corrected mounted on the valve, check input power, input and output signal connections.
Press ASCAN button once, regardless of the position of the actuator, then the actuator will perform the Auto Setting motion:
1) The blue LED flicker
2) Opening (the red LED flickering) for 5 seconds
3) Pause for 2 seconds
4) Fully closing (the green LED flickering)
5) Pause (the green LED on) for 3 seconds
6) Fully opening (the red LED flickering)
7) Pause (the red LED on) for 3 seconds
8) Moving back to the previous position
NOTE: Since the unit is already set at the factory, no further setting is
required unless the user has adjusted the mounting state of Limit Switch or the Potentiometer.

G) Customizing set-points (CH 1 Switch)
- This function is used when the user wants to set different set-points for
fully open and fully closed positions.
- For example, if the user wants to assign 5mA as the set-point for fully
closed position, first of all switch-on (move up) the CH1 switch (switch 4).
Supply a 5mA signal and push the ZERO button once. Hereafter, the
actuator will acknowledge 5mA signal as the set-point for fully closed
position and transmits 4mA feedback signal. Similarly, for setting the
set-point for the fully open position, supply the desired signal (for example,
19mA) and push the SPAN button once. Switch-off (move down) the
CH1 switch to complete the setting.
NOTE: During the Manual Operation mode, the input signal is ignored.

Fully Open 16-21 mA DC
H) Reversal acting (CH 2 Switch)
- This function allows the user to reverse the input and output signals for the
operation of the actuator.
- For standard operation (CH 2 switch down), the input signal of 4mA
operates the actuator to fully close and the actuator transmits the
outputsignal of 4mA. However, when CH 2 switch is on (move up) the
input signal of 4mA operates the actuator to fully open and still transmits
4mA output signal.
- Manually move the actuator to half-open position and push ASCAN button
once to execute the Auto Setting (see 4.7.2 E). Supply signal and check the
operation. ASCAN

I) Delay time
- The actuator starts to move if and only if the change in the input signal
value is greater than the resolution set value (see 4.7.2 J) and when the
signal value is maintained for the duration of the delay time.
- This prevents malfunction of the actuator caused by unwanted signals in
the input signal such as noise and interferences.
- Turning the Delay Time Dial in clockwise direction will increase the delay time
(Range 0.05 to 7.5 seconds).

- The deadband adjusts the limits of the valve’s deviation between an actual position
and a target position. The deadband is set to 0.12mA DC Max.
- Resolution indicates the extent of the reaction on the input signal.
- Low resolution setting may cause the actuator to seek or to unnecessarily respond to
a fluctuating input signal. If so, the resolution must be increased.
- Turning the deadband dial in clockwise direction will increase the resolution
(Range 0.0625mA to 1mA).
