FLOMEC Pulse Access, External Power and Scaled Pulse Module Owner’s Manual

FLOMEC Pulse Access, External Power and Scaled Pulse Module

BEFORE YOU BEGIN

Usage Requirements 

• • This Pulse Access, External Power & Scaled Pulse module is not FM Approved. Therefore, use of this module with an approved metering system voids FM Approval.
  • This module is designed for use with all meters that are equipped with the Q9 display option. The PA-EP-SC module can be field calibrated through the configuration menu options on the Q9 display.

Power Source Requirements 

• This module will function properly with an input voltage between 5.0 VDC and 26 VDC.

UNPACKING / INSPECTION

Inspect 

• After unpacking the unit, inspect carefully for any damage that may have occurred during transit. Check for loose, missing or damaged parts. Shipping damage claims must be filed with carrier.
• See General Safety Instruction, and all Cautions, Warnings, and Dangers as shown.

APPROVAL RATINGS

INSTALLATION

INSTALLING MODULE 

1.  Remove the display electronics from the front of the turbine.
   NOTE: If you are installing more than one module at a time, take care to keep the proper electronics paired with the original turbine.
2.  If your display currently has batteries installed, you will need to remove them to enable the scaled pulse output to function.
3.  Disconnect 2-pin coil connector from display. Make sure coil remains firmly attached to meter body (DO NOT pull on wires or attempt to remove from meter body).
4.  Connect the module to the 10-pin connector located on the backside of the computer electronics (see Figure 2).
5.  Reconnect the coil connector to the 2-pin terminal block on the other end of the computer backside. Once the cables are installed on the display, the housing of the display can be placed on top of the module (see Figure 2).
6.  Install the computer electronics to the front side of the turbine. Tighten the four screws snugly.

WIRING
The Pulse Access module comes pre-wired for external connections to external power and provides an open collector output, which can be set for either raw or scaled pulse output. The wires are color-coded and are to be connected as shown in Figures 3 & 4.

Wire Color	Feature
Red	VCC
Black	GND
White	Pulse Out

NOTE: The pulse output is set to raw pulse output as the default setting on the Q9 display. If your application requires a scaling of the pulse output, refer to the installation instructions to enable the scaled pulse feature and refer to the Q9 owner’s manual for instructions on the configuration of the scaled pulse feature.
NOTE: If using the scaled pulse output feature, use the scaled K-factor in the user interface device.

NOTE: The internal and external options for the pull up resistance and voltage is selectable by the header on the pulse access board (see Figures 4a & 4b).
When the Jumper is on the top two pins, the external resistor required option is selected (Figure 4a). This external resistor can be installed as shown on Figure 3, but could also be built into the existing customer equipment.
When the Jumper is located on the bottom two pins, the internal resistor option is selected (Figure 4b).

Wiring Example 1
Customer’s Equipment:

• Built in Power
• Built in Pull-Up Resistor (via Customer’s Equipment)
• Use Scaled Pulse Output Module’s External Pull-up Resistor Jumper Setting (Fig 4a).

Wiring Example 2
Customer’s Equipment:

• No Built in Power
• No Built in Pull-Up Resistor
• Use Scaled Pulse Output Module’s Internal Pull-up Resistor Jumper Setting (Fig 4b).

Wiring Example 3
Customer’s Equipment:

• Built in Power
• No Built in Pull-Up Resistor
• External Pull-up Resistor added by user.
• Use Scaled Pulse Output Module’s External Pull-up Resistor Jumper Setting (Fig 4a).

OPERATION / CALIBRATION

ADJUSTING SCALED PULSE K-FACTOR 

To set or adjust Scaled Pulse K-Factor settings, refer to the Q9 Owner’s Manual (Non-Agency) Field Calibration Section for further instructions (see below).

TROUBLESHOOTING

Symptom	Possible Cause(s)	Corrective Action
A. No output signal.	1. Incorrect or no input power. 2. Not wired correctly. 3. Broken connection. 4. Defective PC board connector. 5. Defective unit. 6. Batteries installed.	1. Supply correct power requirements.
		2. Check owner’s manual for correct installation.
		3. Check resistance to determine location of break.
		4. Contact distributor or factory for replacement
		5. Contact distributor or factory for replacement.
		6. Remove batteries and cycle loop power.
B. Scaled Pulse output not working or not shown in Q9 configuration options menu.	1. Batteries being installed will disable the Scaled Pulse output feature.	1. Remove batteries, cycle loop power and reconfigure the Scaled Pulse output feature on Q9 display.
C. Pulse output values are not giving accurate total volumes.	1. Customer’s “pulse Input device” (pulses per unit of volume) does not match module pulse output (pulses per unit of volume).	1. Reconfigure module pulse output (or customer’s “pulse input device”) to match in pulses per unit of volume (module output pulses per unit of volume = input pulses per unit of volume).
	2. Q9 display calibration is NOT optimized for best results.	2. Verify Q9 display value is giving correct volume totals.
D. Q9 display value not giving correct volume totals.	1. Q9 display showing velocity, flowrate, or accumulative total instead of batch total. 2. Q9 display calibration is not optimized for best results.	1. Press “bottom button” of Q9 display until correct volume is displayed (see Operation Section in Q9 owner’s manual). 2. If “1” above is not the Issue, see Operation/Calibration Section of this manual.
