Communication

interface

A

Fig.16: Communication interface

The communication interface A is factory-set. A parameterisation kit (ident. No.:

46001269) for actuator communication and parameter setting can be ordered from
KSB. The PC is connected to the actuator via a USB interface and an RJ45 socket using
the communication cable supplied. All actuator parameters can be set with the
software (included in the parameterisation kit). The operating manual is also
included in the scope of supply.

Inputs

Fig.18: Actual process value for process controller (optional)

Terminals 15 to 17 serve to connect the parameterisable actual process value via
4-20mA or 0/2-10V signals supplied by the process sensor, if the optional process
controller in the actuator is used.

NOTE

The binary inputs described below take priority over the setpoint supplied: If the
actuator parameters are set for closed-loop control, the actuator will not follow the
setpoint supplied as long as binary signals are received. Only after the signal has
been removed will the actuator return to the position stipulated by the setpoint.

9 10 11

Fig.19: Galvanically isolated binary inputs

The binary Open/Close signals are connected to terminals 9 to 11. These inputs are
rated for 24VAC/DC as standard. (ðSection9.3.3,Page34) The actuator is
operated in open-loop control mode in this configuration.

EA-C

The output (terminals 14 and 17) supplies 21-40VDC unregulated voltage, 100mA
max.. If a feedback value transmitter is used to supply a setpoint signal for the
optional process controller, a fixed-voltage regulator must be used for 24VDC
voltage supplies. A fixed-voltage regulator is also required when using BOATRONIC
MS-420. For voltage tolerances please refer to the relevant product literature.

5.6 Heating resistor (optional)

On option, a heating resistor can be installed to heat the actuator's terminal
compartment. Condensation inside the actuator if used outdoors, in environments
with highly fluctuating ambient temperatures or high atmospheric humidity will thus
be prevented. The heating resistor inside the actuator is powered by the actuator's
power supply, i.e. separate mains connection is not required.

ü The power supply has been disconnected.

ü The actuator has been secured against unauthorised start-up.

ü The actuator has been moved into the set limit position.

ü The operating manual for the heating resistor included in the scope of supply is

on hand.

1. Open the actuator cover. (ðSection5.4,Page16)

2. For all other steps, see the operating manual supplied.

3. The internal cable must be routed in such a way that it cannot come into
contact with the actuator cover seal and/or moving components.

5.7 Setting the limit switches

The standard limit switches (1) and (2) of the 3-point actuator serve to stop the motor
when the limit positions have been reached. The additional limit switches (3) and (4)
are designed as volt-free changeover contacts for open/closed position feedback.

Fitting of optional limit switches for continuous actuation

ü The power supply has been disconnected.

ü The actuator has been secured against unauthorised start-up.

ü The coupling has been fully extended using the handwheel.

ü The operating manual for the limit switches included in the scope of supply is on

hand.

1. Open the actuator cover. (ðSection5.4,Page16)

2. For all other steps, see the operating manual supplied.

NOTE

For straight-way valves, first set the CLOSED position force-dependent / stroke
dependent, then set the OPEN position stroke-dependent.

1. Use the handwheel to move the actuator into the limit position until the valve
disc touches the valve seat.

ð The position is reached when the valve stem starts to move axially against

the disc spring force in the stem nut.

2. Continue to operate the actuator until the disc springs are slightly pre­compressed (approx. 1.5mm).

3. Loosen the locking screw of the corresponding switching cam.

4. Turn the gear screw to move the switching cam towards the limit switch until
you hear the limit switch click.

5. Tighten the locking screw.

6. Check the setting by repeating the closing action electrically.

ð If the setting for the position is too low, the slip coupling will start making a

rattling noise. Re-adjust the cam as required.

7. On the basis of the lower limit position, read the required stroke on the scale to
set the OPEN position. Set the limit switch to this position.

8. Set the 2 volt-free changeover contacts so that they switch slightly before the
standard switches.

6 Commissioning/Start-up/Shutdown

6.1 Prerequisites for commissioning/start-up

NOTE

Do not operate the actuator electrically before it has been mounted onto a valve.

Before commissioning/starting up the drive, make sure that the following conditions
are met:

▪ Check that the actuator has been properly installed and aligned

(ðSection4.5,Page12) .

▪ Make sure that the operating conditions correspond to the data specified and

those provided on the name plate.

▪ All fastening bolts, connecting elements, and electrical connections have been

properly tightened to the specified tightening torques.

▪ Implement all measures preventing accidental contact with moving and live

parts.

6.2 Commissioning/Start-up

6.2.1 Automatic commissioning of continuous-action and 24V AC/DC 3-point
actuators

The actuator is delivered in "initialised" mode and the green LED is lit. In this mode
the actuator responds to the setpoint supplied or to other operating commands.

If the actuator has been replaced, automatic commissioning must be performed.

Power supply must not be interrupted during commissioning.

If the actuator stroke is blocked during commissioning before the actuator has
reached a set stroke-dependent limit position, the value reached will be saved.

If no torque limit is found during commissioning, or the stroke determined is below
the permissible minimum stroke of 5mm, commissioning is aborted. The actuator
returns to the "non-initialised" state, which is indicated by the green LED flashing
slowly. This will also happen if the actuator has not been initialised correctly.
