Visual Indicators
The Infrared Test LED, as well as several other annunciators, assist you in testing and
troubleshooting the CENTRON OpenWay meter.
Infrared Test LED
The meter is equipped with an Infrared (IR) Test Light Emitting Diode (LED) for testing
meter accuracy; the LED is located at the top of the meter. The pulse weight represented by
the LED is programmable through the PC-PRO+ Advanced programming software for a
CP1SD/T/L meter. The programming software allows a different pulse weight value for the
LED in the following display modes: Normal, Alternate, Test, and Test Alternate. The meter
can be programmed to drive the Test LED with a variety of energy values, depending upon
the energy quantities selected in the configuration.
Annunciators
The CENTRON OpenWay meter is equipped with a variety of annunciators for a more
meaningful display.
Load Indication/Direction Annunciator
The CENTRON OpenWay meter is equipped with a Liquid Crystal Display (LCD) load
emulation indicator. The Load Emulator follows the Infrared Test LED. For each pulse of
the Test LED, the Load Emulator increments one segment. The operation of the Load
Emulator depends on the quantity being pulsed.
 If the quantity being pulsed is “Delivered-Only”, then the Load Emulator scrolls to the
right when energy is being delivered and lights the left arrow when energy is being
received.
 If the quantity being pulsed is “Received-Only”, then the Load Emulator scrolls to the
left when energy is being received and lights the right arrow when energy is being
delivered.
 If the quantity being pulsed is “Delivered and Received”, then the Load Emulator
scrolls to the right when energy is being delivered and scrolls to the left when energy is
being received.
