INSTALLATION
Inspection Inspect the package for damage. If damaged, notify the appropriate carrier immediately.
If undamaged, open the package and inspect the device for obvious damage. Return
damaged products.
Requirements • Job wiring diagrams
• Tools (not provided):
– Digital Volt-ohm Meter (DVM)
– Appropriate drill and drill bit for mounting screws
– TOOL-19, Spring compression tool for AV-600
– TOOL-37, 1-5/8" open-ended wrench
– TOOL-209, 135
Ω and 0 to 7 mA manual positioner
– Two 3/8" wrenches
• Training: Installer must be a qualified, experienced technician
Warning: Disconnect power supply before installation to prevent electrical shock and
equipment damage.
Caution:
• Use electrostatic discharge precautions (e.g., use of wrist straps) during installation and
wiring to prevent equipment damage.
• Make all connections in accordance with the wiring diagram and in accordance with
national and local electrical codes.
Use copper conductors only.
• Do not exceed the ratings of the device(s).
• Do not apply power to the unit unless the damper linkage and/or the valve assembly
have been installed.
• Avoid locations where excessive moisture, corrosive fumes, or vibration is present.
• Do not install insulation on any part of the actuator.
Notes:
1. The 4 to 20 mAdc controller is supplied by others.
2. The controller has setpoint and throttling range (proportional band) adjustments. The controller may also
incorporate I (integral) and D (differential) functions.
3. To expose the startpoint adjuster, remove the plug button from the base of the actuator by prying it off with a
screwdriver. With a 4 mA controller input signal present, use a small, single-slotted screwdriver to adjust the
actuator startpoint potentiometer so that the actuator shaft just begins to extend.
4. The output can be either direct-acting or reverse-acting:
Direct-Acting (DA) Output: An increase in the measured media causes the controller output (4 to 20 mA
signal) to increase.
Reverse-Acting (RA) Output: An increase in the measured media causes the controller output (4 to 20 mA
signal) to decrease.
Sequence Of Operation:
An increase in the 4 to 20 mAdc signal causes the MPR-561X or MPR-563X actuator shaft to extend. On
power loss to the actuator, the shaft retracts.
