WARNING
INSTRUCTION MANUALS
Do not install, maintain, or operate this equipment without reading, understanding and following the
proper ABB Inc. instructions and manuals, otherwise injury or damage may result.
RETURN OF EQUIPMENT
All equipment being returned to ABB Inc. for repair must be free of any hazardous materials (acids,
alkalis, solvents, etc). A Material Safety Data Sheet (MSDS) for all process liquids must accompany
returned equipment. Contact ABB Inc. for authorization prior to returning equipment.
Read these instructions before starting installation; save these instructions for future reference.
WARNING
Stay clear of moving components when performing procedures that require the
equipment to be energized. The equipment can operate automatically. There is a
risk of entanglement of body parts if caution is not observed. When possible,
remove the supply source or remove the equipment from the process before
servicing.

1.0 SPECIFICATIONS / FEATURES
LP linear piston actuators are used to control the
position of air dampers or louvers on furnaces,
boilers, and air distribution systems. They are
also used on burner and SOFA Tilts. They are
suitable for Windbox damper control in NOx
reduction control systems.
Operation with TZID-C Smart Positioners offers
digital communication, self-calibration,
diagnostics and monitoring functions. The
“AutoStroke” feature calibrates and tunes itself
automatically.
FEATURES :
High resolution, sensitivity, and fast response
with proven AV and TZID-C Positioners.
• Cylinders available with Buna-N or Viton
seals.
• Temperature range up to 250oF with
AV15, 185oF with TZID-C.
• Easy adaptability to air dampers and
louvers via clevis and pivot pin
mounting.
• Drop in replacement for many “older”
piston actuators.
• Available with built-in 4 to 20ma.
position feedback.
Linear Piston Actuator Assemblies
The LP series of damper drives provide a linear
actuation solution that is ideally suited for
applications like Windbox-dampers. The
conventional assembly, which uses the AV
Positioner series, offers a high-temperature
option up to 25oF. In comparison, our digital
solution allows for operation up to 185oF, plus
the added features of digital control.
LP sizes range from a 2.5” diameter cylinder
with a 5” stroke (2.5”x 5”) up to a 12”x 14”
diameter cylinder. The most common sizes,
2.5”x 5” and 4”x 4,” are readily available.
TZID-C Digital Features
• Microprocessor-based
• Local keypad, two line LCD and
position indicator
• Easy local configuration and operation
• Digital communication via HART,
FOUNDATION Fieldbus, and Profibus
• Remote configuration and monitoring
Configurable operating parameters
• Easy set-up of direct/reverse action, limit
stops, etc.
• Integrated position feedback
• Analog and/or digital feedback without
additional external devices to calibrate and
maintain
• Diagnostics and self-monitoring capabilities
• Easy trouble-shooting and preventive
maintenance
• Immunity to shock and vibration allows
installation in high vibration areas

2.0 THRUST RATINGS
The basic thrust rating of a
pneumatic piston is equal to the area
of the piston times the supply
pressure. The minimum supply
pressure for both the TZID-C and the
AV1 is 20 psi.
The maximum supply pressure for
the TZID-C is 90 psi and 125 psi for
the AV positioner.
The area of the piston is A = πD2/4.
Subtract approximately 10% for
friction losses and because the rod
side of the piston has less area. An
example is shown for an 80 psi air
supply:
To find the lever length that would result
in 90orotation of the damper shaft,
multiply the cylinder stroke length by
0.707.
Please refer to the individual Product

and TZID-C Positioner performance.

3.0 MODEL NUMBER DETAILS
“Simple Cylinder” type Linear pneumatic piston actuators are supplied with either type AV conventional
or type TZID intellegent positioners mounted on the cylinder. Cylinders are supplied with a threaded
clevis on the rod end and a standard MP pivot on the base.
The cylinders can be supplied with either Buna-N nitrile rubber seals suitable for 200oF operation or Viton
seals suitable for 300oF operation. The Buna-N seals have a lower breakaway pressure, offering
smoother modulating control. High temperature Viton seals are inherently higher friction and tend to stick
and breakaway, causing somewhat jerky motion. The operating temperature for the AV15 & AV16 is
250oF. All other positioners have a 185oF maximum ambient. Buna-N seals are recommended unless
temperatures > 200oF dictate Viton.
Please refer to the individual Instruction Books for the AV and the TZID-C for
details on the two types of Positioners.
