MP913C1066-1 is a Honeywell pneumatic damper actuator used within the Honeywell pneumatic damper-control architecture. It provides the specified pneumatic damper actuator function while retaining the complete order code, hardware execution and receiving-system compatibility during replacement. Its documented effective diaphragm area (cm2 ) is 45 cm2.
Board Setup: MP913C1066-1 performs the pneumatic damper actuator function within the Honeywell MP900 pneumatic actuators. The retained documentation identifies effective diaphragm area (cm2 ) as 45 cm2; apply that value only to this documented execution.
Match the complete label, hardware form and functional position before transferring any setting, cable or termination from the removed unit.
System Context: approve MP913C1066-1 only for the documented Honeywell pneumatic damper-control architecture. Compare rack, carrier or panel generation, connector keying, terminal numbering and all paired assemblies with the installation drawings.
Photograph both sides and the installed position before removal so revision markings, jumpers, addressing and channel allocation can be reconstructed accurately.
System Testing: isolate the equipment, remove stored energy and inspect the receiving hardware before installing MP913C1066-1.
Restore power in the approved sequence, review status and diagnostics, then test every affected control, signal, relay, communication, protection or monitoring path against the commissioning record.
Verify that the supplied item is marked MP913C1066-1 and that its pneumatic damper actuator form, faceplate, connectors and printed revision agree with the approved Honeywell MP900 pneumatic actuators receiving record.
Retained product evidence for this execution includes Effective diaphragm area (cm2 ): 45 cm2; Stroke (mm): 100 mm. Use photographs of the label and installed position to resolve ambiguity before shipment or installation.
For MP913C1066-1, provide the installed Honeywell pneumatic damper-control architecture, required condition, quantity, receiving slot or mounting position and every connected terminal, cable or carrier assembly.
Record revision restrictions, configuration or calibration dependencies, testing requirements and required certificates so the quoted pneumatic damper actuator matches the maintenance scope.
Confirm the current OEM lifecycle stage for MP913C1066-1 against manufacturer records at quotation. The supplied pneumatic damper actuator is matched by its complete hardware identity, revision and included assemblies.
Any alternative is proposed only after the receiving Honeywell pneumatic damper-control architecture, interfaces, configuration dependencies and commissioning requirements have been reviewed.
