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.

LP LINEAR PISTON ACTUATORS INSTRUCTION MANUAL

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.
