Energy Pulsing
Five Calibration Pulser modules are preconfigured at the factory for energy
pulsing applications. One of these modules is programmed to send kWh pulses to
the LED on the back of the meter. The remaining four (configured for imported/
exported kWh and kVARh pulsing) can be configured to send energy pulses to any
digital output port. Edit the appropriate Calibration Pulser or Pulser module’s Port
setup register, and set it to the port you want to send the signal through (D1, D2,
D3 or D4, or IR1).
LED Energy Pulsing
The LED port (L1) controls the LED on the back of the meter. This port is used for
kWh pulsing by default; LED 1 on the back of the meter pulses every 1.8 Wh. If you
wish to configure the LED for other energy pulsing applications (i.e. kVAh, kVARh),
you must first disable the default kWh pulsing. Use the front panel to disable kWh
pulsing as follows:
1. From the SELECT SETUP menu, choose ADV METER SETUP > CALIBRATION
PULSER MODULES > KWH IMP LED, and highlight the Port setup register and
press the round button.
2. From the list of available ports, select NOT USED.
These steps remove control of the L1 LED from the kWh IMP LED module. You
can also disable the kWh pulsing using Designer. Select the kWh imp LED
Calibration Pulser module and disable L1 by setting the Port setup register to NOT
USED.
Configuring Other Energy Pulsing Applications
Now that you have the L1 port free to assign a pulse to, you can assign other Pulser,
Digital Output, or Calibration Pulser modules to it. Using the front panel, assign a
Pulser module as follows:
1. From SELECT SETUP choose ADV METER SETUP, then select the new module type
and the module you wish to use for pulsing the LED.
2. Scroll down and select the Port (e.g. PU2) setup register, then choose L1.
You can also configure LED energy pulsing from Designer. Select the Digital
Output, Pulser, or Calibration Pulser module you wish to use and set its Port setup
register to L1.
Using the Relay Expansion Board (REB Option)
The REB option (Relay Expansion Board) allows for custom digital output
applications using specific Grayhill relay units. The REB option provides four slots
where you can plug Grayhill digital output hardware modules. There are nine
Grayhill hardware modules of varying functionality available. The relays are
purchased separately.
As with onboard digital outputs, the Pulser, Calibration Pulser, and Digital Output
modules can be used to control the functions of the external relays. Set the
module’s Port setup register to the digital output port (D1 to D4) that the relay is
connected to.
