Product Usage Instructions

Mounting

For hand-held models, use the spring-return hanger to suspend the Remote Setpoint in a convenient location. No additional mounting is required. Panel- mount versions require a cutout as per the Mounting Dimensions diagram. Provide at least one inch of clearance behind the panel for the ACQ101. Follow the instructions provided in the manual for mounting.

Wiring

Hand-held models come with an integral coiled cord with an MS Connector for direct connection to compatible controllers. For panel-mount ACQ101B, refer to the Wiring Diagram provided in the manual. Use Part Number KW01001 cable assembly for wiring connections.

Frequently Asked Questions

Q: Can I adjust the slope setpoint on the ACQ101A and B Remote Setpoint Modules?

A: Yes, when used with compatible controllers, the slope setpoint can be adjusted anywhere on the infinite resolution scale within 10% of zero slope.

Q: What accessories are available for the ACQ101A and B Remote Setpoint Modules?

A: Part Number KW01001 coiled cord assembly is available to extend connections between the panel-mount ACQ101B and compatible controllers with MS Connectors or Proportional Level Controllers.

DESCRIPTION

The ACQ101A and B Remote Setpoint Modules adjust slope to a setpoint other than vertical. When used with the Danfoss W894A Proportional Level Controller or R7232 or ACE100A Proportional Indicating Controllers, the slope setpoint can be set anywhere on the infinite resolution scale within 10% of zero slope. The ACQ101A is hand-held and has a coiled cord and MS Connector for hookup. The ACQ101B is mounted in the cab panel and has a terminal strip for electrical connections

FEATURES

• The ACQ101A hand-held model has a spring-loaded hanger that easily clips to railings, pipes or bars, affording extensive freedom about the machine for the operator.
• The ACQ101 can be rotated in any direction without affecting operation.
• Shock and vibration-resistant, both models also resist corrosion and moisture.
• The ACQ101A and B are easy to install. The MS connector on the hand-held model plugs in and screws tight. The panel mount model mounts on a flat surface 3 by 6 inches or larger. Four connections to the terminal strip complete the hookup.

ORDERING INFORMATION

ACCESSORIES

Part Number KW01001 coiled cord assembly extends to 10 feet and provides all necessary wiring connections between the panel-mount ACQ101B and the R7232 Proportional Indicating Controller with MS Connectors or the W894A Proportional Level Controller. It comes completely assembled with MS Connector on one end and spade lugs on the other

• OPERATING TEMPERATURE
  • 0 to 140°F (-18 to +60°C).
• STORAGE TEMPERATURE
  • 40 to +170°F (-40 to +77°C).
• WEIGHT
  • Hand-held model: 1 1/2 lbs. (680 grams).
  • Panel-mount model: 7 ounces (198 grams).

ENVIRONMENTAL

SHOCK
Withstands a shock test designed for mobile equipment devices that consists of three shocks of 50 g’s and 11 milliseconds duration in both directions of the three major axes for a total of 18 shocks.
VIBRATION
Withstands a vibration test designed for mobile equipment devices that includes two parts:

1. Cycling from 5 to 2000 Hz over a range of ±1.5 g’s to ±3.0 g’s for a period of one hour (if there are four resonant points), for two hours (if there are two or three resonant points), and for three hours (if there is one or no resonant point). The cycling test is performed on each of the three major axes.
2. Resonance dwell for one million cycles over a range of ±1.5 g’s to ±3.0 g’s for each of the four most severe resonant points on each of the three major axes

MOUNTING

Hand-held models have a spring-return hanger designed for suspending the Remote Setpoint in any convenient location. No mounting is required. Panel- mount versions require a cutout of the size shown in the Mounting Dimensions diagram. At least one inch of clearance should be provided behind the panel for the ACQ101. Drill 3/16 inch clearance holes in the location shown in the Mounting Dimensions diagram. Remove the nuts from the lugs at the back of the front plate. Insert the lugs through the clearance holes and replace the nuts from the back of the panel.

MOUNTING DIMENSIONS

WIRING

The hand-held models have an integral coiled cord with an MS Connector that plugs directly into the R7232 Proportional Indicating Controller or W894A Proportional Level Controller. If an R7232 Proportional Indicating Controller with terminal strips is to be used in conjunction with the hand-held ACQ101A, mount a Bendix Type Number MS3102A16S-8P Danfoss Part Number K03992) receptacle on a panel and wire the receptacle to the corresponding letters on the R7232terminal strip. Wiring for the panel-mount ACQ101B is shown in the Wiring Diagram. The ACQ101B has terminal strips for wiring connections. If an R7232 Proportional Indicating Controller with MS Connectors or W894A Proportional Level Controller is to be used in conjunction with the ACQ101B, order Part Number KW01001 cable assembly. The cable assembly includes spade lugs at one end and an MS Connector at the other end to provide all wiring for the panel-mount model.

TROUBLESHOOTING

The ACQ101 Remote Setpoint will provide extended trouble-free operation and should not need servicing under normal operating conditions. Be sure the ACQ101 is malfunctioning before replacing it.

1. Check the wiring. The connector or spade lugs may have been disconnected. Check all wires, look for cuts or evidence of pinching.
2. Check for continuity. If a VOM is available, check resistance between pins/terminals A and C for 2500 ohms. Check continuity between pins/terminals A and B, B and C while rotating the dial. Resistance should approximate the values shown in the Resistance Vs. Dial Position diagram.
3. If another ACQ101 is available, connect it in place of the existing one. Change the slope setpoint and observe the operation. If the replacement ACQ101 corrects the malfunction, replace the original unit.
4. Check the operation of the servo valve, proportional indicating controller and sensor
