GENERAL DESCRIPTION

The MTC-6000 is a Micro-Processor based Master Time Clock. The unit will provide

synchronization for a wide variety of industry standard secondary wall clocks, payroll recorders,

time & date stamps, and other time keeping devices.

The output circuits may be individually programmed for control of bells, lights, heating and

air conditioning, and other devices which can be scheduled for operation based on the time and

day. Programing for these circuits may be TIME ON - TIME OFF or TIME ON -

DURATION. Programing can be by individual day, 5 day (Mon.-Fri.), or 7 day.

The clock time base, in normal operation, is synchronized with the 60 Hz AC power line. During

power failures, the time base is accurately maintained by a back up battery powered oscillator.

The back up battery system uses a lithium energy cell with a design life of ten years. The battery

maintains timing and circuit programing during a loss of primary power.

Holidays may be programmed 12 months in advance. The Holiday feature will inhibit the

automatic operation of the Output Circuits during a programmed holiday.

Automatic daylight savings time changes. (May be turned off)

Automatic updating of Impulse secondary clocks after a power failure. The MTC-6000 records the

time of power failure and the current time. When power is restored, correction pulses are sent to

the clocks.

All operator programing functions are easily performed from the front panel. A security access

code prevents unauthorized programing changes.

INSTALLATION

1. As you unpack the clock, check for

shipping damage to the carton or clock.

Report any damage to the carrier.

2. The MTC-6000 is designed for mounting

in a standard 19 inch rack.

3. The clock must be installed in

accordance with all local wiring codes.

The chassis ground connection must be

connected to a good earth ground circuit.

The terminal strip provided for external

wiring connections is a pressure plate

type, the terminals are rated for clamping

two 12 ga. wires.

4. Synchronous Wired Secondary Clocks: A

typical connection for 120 VAC or 24

VAC synchronous wired clocks is shown

at Figure 2.

5. Impulse Secondary Clocks: Figures 5 & 6 show typical connections.

6. Before applying power to the Master Clock, assure that all wire runs to and from the output

circuits and clock correction circuits are not shorted or grounded.
