GENERAL DESCRIPTION

The Large Display is a versatile display that can be configured as a single or
dual counter with rate indication, scaling, serial communications and a dual
relay output. There are also basic models that have a single counter with
direction control only (no scaling or relay output).
The 4 & 6 digit displays are available in either 2.25" or 4" high red LED digits
with adjustable display intensities. The 2.25" high models are readable up to 130
feet. The 4" high models are readable up to 180 feet. All versions are constructed
of a NEMA 4X/IP65 enclosure in light weight aluminum.
The 6-digit programmable models have two signal inputs and a choice of
eight different count modes. These include bi-directional, quadrature and anti-
coincidence counting, as well as a dual counter mode. When programmed as a
dual counter, each counter has separate scaling and decimal point selection.
Rate indication is available on the programmable models only. The rate
indicator has separate scaling and decimal point selection, along with
programmable display update times. The meter display can be toggled either
manually or automatically between the count and rate values.
The programmable models also come with a dual Form C relay output and
RS232 or RS485 serial communications. The outputs can activate based on
either counter or rate setpoint values. An internal batch counter can be used to
count setpoint output activations.

SAFETY SUMMARY

All safety regulations, local codes and instructions that appear in this and
corresponding literature, or on equipment, must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment connected to
it. If equipment is used in a manner not specified by the manufacturer, the
protection provided by the equipment may be impaired.
Do not use this unit to directly command motors, valves, or other actuators
not equipped with safeguards. To do so can be potentially harmful to persons or
equipment in the event of a fault to the unit.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.

  • Page 4: Wiring Overview

    WIRING OVERVIEW Electrical connections are made via pluggable terminal blocks located inside the meter. All conductors should conform to the meter's voltage and current ratings. All cabling should conform to appropriate standards of good installation, local codes and regulations. It is recommended that the power supplied to the Front meter (DC or AC) be protected by a fuse or circuit breaker.

    3.4 INPUT WIRING The Large Display has two signal inputs, A and B. These inputs are wired to All other models are non-programmable and provide Count with Direction terminal block TBB located inside the unit on the right side. Mode only. Input A accepts the count signal, while Input B controls the count direction (up/down).
