GENERAL DESCRIPTION

The Large Display Timer and Cycle Counter is a versatile display that

functions as an Elapsed Timer or Preset Timer, with full-featured user

programmability. The meter includes a built-in Cycle Counter, relay output and

serial communications capability. The 6 digit displays are available in either

2.25" or 4" high red LED digits with adjustable display intensity. The 2.25" high

models are readable up to 130 feet. The 4" high models are readable up to 180

feet. Both versions are constructed of a NEMA 4X/IP65 enclosure in light

weight aluminum.

The Timer has two signal inputs and eight input operating modes. These

modes provide level active or edge triggered start/stop operation. The Timer

features 18 selectable timer ranges to cover a wide variety of timing applications.

The built-in Cycle Counter can be linked to timer operation to count timing

cycles, or function as a totally independent counter, accepting count speeds up

to 500 Hz. The display can be toggled either manually or automatically between

the Timer and Counter values.

In addition to the Timer/Counter inputs, a programmable User Input is

provided to perform a variety of meter functions. DIP switches are used to

configure the inputs for current sinking (active low) or current sourcing (active

high) operation.

The Setpoint Output can be assigned to the Timer or Counter value, and

configured to suit a variety of control and alarm requirements. The meter also

includes RS232 or RS485 serial communications.

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.
