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 requires an input power of 5.0-26 VDC (24 VDC is
recommended).
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.

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.

INSTALLATION (continued)
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.

INSTALLATION (continued)
WIRING (continued)
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).
