1. SAFETY
Carefully read the present Operating Instructions, especially the following safety precautions prior to installation
and operation.
Caution
Potentially hazardous situation which could result in minor injury.
Also indicates a risk which may cause material damage.
Attention
Potentially harmful situation which can result in damage to the product or an object in its
environment.
Danger
Imminently hazardous situation which will result in death or serious injury.
Warning
Potentially hazardous situation which may result in death or serious injury.
Tip: Instructions for use or other useful information.
1.1 Intended use
baelz 373-E66-150-22 motorized linear actuators are controlled by three-point control or constant control in combi-
nation with the PEL positioning electronics. The linear actuators of the series described in this manual are intended
for the adjustment of the valve stroke.
To ensure their intended use, make sure that the above type identication complies with the identication label of
the linear actuators before starting any activities. The actual technical data of the linear actuators and the power
supply requirements are the specications indicated on the identication label.
Any use other than the intended use mentioned above, different tasks, and operation with other power sources
than those permitted, is considered to be improper use. In case of improper use, the operator shall be solely liable
for the risk presented to persons and the device as well as other property!
The intended use also comprises compliance with the accident prevention regulations and the DIN VDE standards
of the German Institute for Standardization and the Association for Electrical, Electronic & Information Technolo-
gies. It also implies working in accordance with the safety requirements when performing all activities described in
the present Operating Instructions, under consideration of general technical rules and regulations.
1.2 For the operator
Make sure the Operating Instructions are kept permanently available and easily accessible at the site of operation
of the linear actuators!
During set-up, operation and when performing maintenance procedures on the device, observe the applicable oc-
cupational safety regulations, accident prevention regulations and the DIN VDE standards of the German Institute
for Standardization and the Association for Electrical, Electronic & Information Technologies. Observe compliance
with any possibly applicable additional regional, local or in-house safety regulations.
Make sure that any person assigned by you to perform the activities described in the present Operating Instruc-
tions, has read and understood these instructions.

2.5 Operating conditions
In case of extreme variations in ambient temperature and high humidity levels, installation of a heating resistor is
recommended to minimise condensation in the actuator.
Actuator covers with suppression of thermal bridges (dual covers) are recommended.
● Connect the heater HZG as shown in the connection diagram.
● After installation, put the device immediately into operation.
The actuators are suitable for installation in industrial plants, in waterworks and power plants with a low pollutant
concentration.
For use outdoors or in an environment with a high pollutant concentration, such as heavy trafc areas, industrial
areas (chemical plants, sewage plants, etc.), coastal areas and the open sea, the actuators must have external
parts made of non-corrosive material and must be provided with a special coating.
When used outdoors, the actuator must be protected with an additional cover against
● rain
● direct sunlight
● strong draught
● dust

3. TRANSPORT AND STORAGE
Risk of injury caused by failure to observe the safety regulations!
● Wear the required personal and other protective equipment.
● Protect the linear actuator from impacts, shock, vibration and similar inuences.
● Store the linear actuator (and, if necessary, the complete actuator/valve assembly) in a dry place.
● Observe the transport and storage temperature of -20 to +60°C.
4. MOUNTING
4.1 Mounting position
When mounted with the connecting rod in horizontal position, mount the linear actuator such that
the two rods of the yoke are positioned on top of each other in the vertical plane.
Damage caused by missing valve!
● If the linear actuator is operated without a valve, the missing stop may cause damage to the actuator.
The actuator must therefore never be operated without a valve.
● Allow for about 200 mm space above the cover at the site of installation.
● Check the work environment before mounting the actuator and before putting it into operation:
● Make sure that the valve is correctly installed. For detailed information, refer to
the valve's installation instructions.
● Determine the mounting position of the linear actuator. Do not mount linear actuators in downward
position.

4.2 Assembly with valve
Prior to assembly check that
● the specications of the linear actuator comply with the operating conditions.
● the valve is complete (yoke on actuator or on valve).
● the connections on valve and actuator match.
Figure 6: Assembly with valve
It must be ensured that the connecting rod of the actuator and the valve spindle are correctly aligned. A misalign-
ment will lead to power loss or premature wear.
When supplied with integrated switching and signalling unit, the stroke may have to be adjusted.
