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.
The protective conductor terminal is bonded to conductive
parts of the equipment for safety purposes and must be
connected to an external protective earthing system.
