The PULSAPRO ® XAE is rated for NEMA 4x and 7 hazardous locations as identified on the controller nameplate.
Hazardous location – A hazardous location is defined as an explosive atmosphere due to the presence of flammable gasses, liquids, vapors, combustible dust, or ignitable fibers.
DESCRIPTION
The XAE is an electromechanical servo controller dedicated to the PULSAPRO diaphragm metering pump series. The unit is physically attached and integrated into the pump's design. The controller allows for precise adjustment of output flow of a process media by means of stroke length positioning.
The XAE is designed for the international industrial market. The analog control signals offer flexible remote control. They are isolated from earth ground for improved protection and reliability.
The XAE is designed to simplify and automate the calibration of the analog signals. Analog signal calibration is accomplished by simple push button entry. Calibration functions must be completed while the internal circuitry of the unit is accessible, and therefore at a time when the surrounding environment is considered safe for electronic work.
XAE STANDARD FEATURES
- Electronic Stroke Length Control
- NEMA 4x
- 4-20mA input and output
- AUTO/MANUAL Pull Switch - Manual over-ride of output setting
- (3) Switch closure inputs for Interlock, Alarm and Run
- (3) Relay outputs for Auto/Manual, Alarm and Run status
TheXAE uses a switching power supply that can accept power from 100 to 240 VAC, at 50 to 60 Hz.
INSTALLATION AND WIRING
- Disconnect power at the source (follow your local Lock-Out-Tag-Out procedures).
- Grasp the cover from the outside – one hand on each side - and rotate counterclockwise looking from the external knob end towards the pump.
When cover threads are clear pull the cover straight back off over the internal components.
Cover Re-installation
- Disconnect power at the source (follow your local Lock-out-Tag-out procedures).
- Verify that the threads of the cover and based plate of the XAE are clean and well-greased.
- Inspect wiring to assure it is neat and secured away from the cover surface.
- Slide the open end of the enclosure over the electronic assembly. Assure no wires are caught or pinched.
- Rotate the cover clockwise to tighten it onto the base plate.
- Continue to rotate the cover until the edge contacts the flange on the base plate.
- Check the cover contacts the flange with no air gaps.
- When wiring is completed and cover is properly replaced, the XAE is now ready for operation. Remove Lockout-Tag-out protection and restore power. See the Electrical Wiring section for further details.
- The Neutral wire is connected to the terminal labeled “N” (the corresponding wire color is blue).
- The Line wire is connected to the terminal labeled “L” (the corresponding wire color is brown).
- The Earth wire is connected to the terminal labeled with the “Ground” symbol (the corresponding wire color is green with yellow stripe).
The INTERLOCK input is designed to grant the actuator permission to operate. The INTERLOCK must be activated (closed) for RUN and ALARM inputs to work. The INTERLOCK will also reset the XAE whenever it is enabled. This can be useful will reset the XAE - clearing any alarms present.
NOTE: THE RESET FUNCTION WILL DELAY OPERATION (THE ABILITY TO RESPOND TO A CONTROL SIGNAL) BY 10 SECONDS FROM THE TIME THE INTERLOCK INPUT IS CLOSED. FOR FASTER RESPONSE, USE THE RUN INPUT.
The input is designed for a dry contact (switch) input. It must be an un-powered, dry contact only. When the contact is closed the actuator will perform a Power-On-Reset before following the RUN and ALARM commands. When the contact is open the actuator will disable the drive motor and the RUN and ALARM relay outputs (the AUTO/MANUAL output will still reflect the status to the AUTO/MANUAL switch).
Make connections to J6-1 and J6-2 as shown. The wire must be between 12 and 24 AWG (14 AWG recommended). The insulation should be stripped back approximately 0.25 inches (6.5mm).
Loosen the terminal screws and insert the stripped wire end fully into the terminal. Tighten the screw to 3.5 in-lbs. (0.4 Nm) to secure the conductor. Make certain that the terminal grips the wire, not the insulation.
When the XAE is added to a pump, it must be aligned to the pump before the two parts are coupled. This is done by setting the stroke length of the Pump to 50% and adjusting the XAE to 50% before coupling.
- Set the pump stroke length to 50%. Prepare the XAE to operate un-coupled from the pump. Identify the output shaft and stay clear.
- Move the AUTO/MANUAL switch to the MANUAL position.
- Identify the hazardous locations to all personnel in the immediate area (see SETUP section in this document for further information). Assure the environment is safe.
- Turn power on to the XAE. Wait of the system to boot and the L3 LED to come on BLUE (MANUAL MODE).
- Follow the MECHANICAL (0%/100%) CALIBRATION procedure found in the Appendix. Stop after step #5.
- Wait for the L2 and L3 LED’s to turn on RED (the adjustment motor will stop).
- The XAE is now at its 50% position. Remove power.
- Align the pump stroke adjustment knob coupling to the XAE. If necessary, adjust the pump coupling (using the knob) up to ¼ of a turn to align the two coupling parts.
- Remove 2 of 4 of the side cap bolts as shown below (7/16” for the 680-880, 5/8” for the 7120). Install the bracket half to the pump then to the XAE using the supplied hardware:
- Install the second bracket half.
- Apply power and complete the Mechanical Setup Procedure.
If a replacement oscillating housing assembly for the pump was supplied with the new cover assembly:
o Make a note of the position of the control block by marking a tooth on the bevel gear and making an
aligning mark on the housing (see step #5).
- Remove the cotter pin and castle nut from the round end of the new shaft (see step #7).
- Pull the brass washer off the end of the shaft (see step #8).
- Pull the round shaft out of the bearing on top of the oscillating housing (see step #12).
- Pull the shaft out of the bevel gear.
- Keep these parts in a clean location as you will need them at a later step.
- Replace the oscillating housing in the pump. Set the oscillating housing at its 50% point. Note this step is beyond the scope of this procedure. Contact Technical Services if further guidance is required.
Go to the pump assembly. Apply general purpose grease to the bevel gear, bearing bore, and both sides of the bearing block (where the bevel gear and brass washer sit) on the oscillating housing before assembly.
Use 2 people to install the cover assembly. One person will lift the cover assembly and the second person will help line it up with the pump. The second person will also guide the round end of the adjustment shaft through the bevel gear and the bearing. Note - you will need to mesh the bevel gears and align the cross pin with the slot in the gear as you insert the shaft.
Install the (6) cover screws finger tight.
Grease and replace the Brass washer, and castle nut. Tighten the nut by hand to take up the slop in the shaft then loosen by one slot position to align the slots in the nut with the hole in the shaft. The shaft needs to turn freely in the beaning. Install the cotter pin and spread the end.
Remove the XAE cover threading it off the back plate by turning it counterclockwise.
Replace the conduit and power and signal wiring (refer to section 8.8 Power Wiring).
Move the AUTO/MANUAL switch on the XAE to the MANUAL position.
Identify the hazardous locations to all personnel in the immediate area (see SETUP section in this document for further information). Assure the environment is safe.
Turn power on to the XAE. Wait for the system to boot and the L3 LED’s to come on BLUE (MANUAL MODE).
Complete Analog Input / Analog Output calibration as required. Note – AUTO/MANUAL switch will need to be positioned in the AUTO setting (pushed in) to follow the signal.
Applying 4-20mA a signal, exercise the actuator between the 0% and 100% position. If the XAE does not achieve the 0% and 100% positons, follow the MECHANICAL (0%/100%) CALIBRATION procedure found in the Appendix. The procedure includes pictures of the PulsaPro (on the left below) – these should be ignored. Instead, refer to the dial indicator (on the right below) on the cover assembly for the actual 0% and 100% positions.
Remove power and replace the XAE cover. Tighten it onto the back plate so that it is tight to the flange.
Replace all covers/sub-covers removed in the above procedure (e.g., the front sub cover).
Hand tighten all screws.
Extend the bleeder line from the bleeder at the front of the pump to the fitting in the cover at the back of the pump.
The pump/control is now ready to return to service.
