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

115 VAC

POWER INPUT

1. As you unpack the clock, check for

LINE CORD

shipping damage to the carton or clock.
Report any damage to the carrier.

FUSES

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.

FRONT PANEL CONTROLS

1. The ENTER button is used to enter selected data into the memory. This button is active in

the program mode.

2. The CANCEL button is used in the review mode to cancel programmed times and dates
that are no longer needed. It is also used to exit the program mode and return the clock to
normal operation.

3. The AHEAD and BACK buttons are used to increment the display to the time or date to be
programmed. They are also used in the Review mode to observe multiple programmed
times for the output circuits and multiple holidays. These buttons are active in the program
mode.

4. The MODE button is used to select the functions to be programmed or reviewed.
An illuminated indicator will show the selected mode. Each time the MODE button is pressed,
the next indicator in sequence will be illuminated. The Time Set function allows the
setting of current time, day, month, date and year. The Holiday function allows setting of
holiday dates. The Duration, On and Off modes are used to program the output circuits.
The Erase mode is used to bulk erase all programmed memory times and dates except
the current time and date. The MODE button is active in the program mode.

5. The REVIEW button is used in conjunction with the MODE button to check the
programmed times and dates. The review button is a push ON push OFF control, it must
be turned OFF to advance the MODE function. It is active in the program mode.

6. The SELECT button is used with the mode function to program the month, date and year in
the Time Set mode, and the beginning and ending month and date in the Holiday mode. The
SELECT button is also used in the review mode to observe the beginning and ending dates
of holidays. This button is active in the program mode.

7. The CIRCUIT button is used in the Duration, On and Off modes to select the output circuit to
be programmed. It is active in the Duration, On and Off modes.

8. The DAY button is used in the On and Off modes to select the appropriate day or days for
programing the output circuits. It is used in the Time Set mode to set the current day of the
week.

9. The IMPULSE SECONDARY CORRECTION switch is used as an aid for initial
synchronization of secondary impulse clocks. Placing the switch in the RAPID position
causes the clocks to advance to the 58th or 59th minute at a rate of 30 steps per minute.
Returning the switch to the OFF position returns control of the secondary clock to the Master.
Placing the switch in the HR/MIN position causes the clocks to advance at the rate of 30 steps
per minute until the switch is returned to the OFF position. This switch is active in the
program Time Set mode. This switch must be in the OFF (center) position except while
advancing the Impulse Secondary Clocks.

10. The WIRED SYNC SECONDARY CORRECTION switch is used as an aid for initial
synchronization of secondary wired synchronous clocks. Placing the switch in the HOUR
position sends one hourly correction signal to the secondary clocks. Placing the switch to the
12 HOUR position sends one 12 hour correction signal to the secondary clocks. Move the
switch to OFF to return secondary clock control to the master. This switch is active in the
program Time Set mode. This switch must be in the OFF (center) position except while
advancing the Wired Synchronous secondary clocks.

11. The CIRCUIT CONTROL switches are provided for manual control of the output circuits. The
OFF position turns the output circuit OFF regardless of the programing. The AUTO position

22

places that output circuit under control of the program. The ON position places that output
circuit ON regardless of the programing.

PROGRAMING

1. SET UP

After the initial installation, the clock must be tailored for the desired operation. All setup is done
from the front panel using access codes and the display. The following options are
programmable:

Daylight Savings Time ON or OFF (Default is ON)
12/24 Display (Default is 12 Hour format)
Synch-Wired Clock Type (Default is Midwest Time Control Clocks)
Impulse Clock Type (Default is 59 minute, no 12 hour correction)
BAUD Rate (Default is 9600 BAUD)

2. SECURITY ACCESS CODE

A Security Access Code must be entered before a time set, a program change, addition or review.
The code is a simple and easily remembered front panel button sequence (ENTER, BACK,
CANCEL and AHEAD). When these buttons are pressed in the correct sequence, the Time Set
indicator will illuminate. Program changes can be made any time the program indicators are
illuminated. To leave the Program mode, press the CANCEL button. This restores the unit to
normal operation. The Program Control mode will time out automatically 90 seconds after the last
button is pressed. This prevents leaving the clock unattended in the program mode. A Program
Indicator must be illuminated during all programing operations.

For units equipped with the RS232-COM Options, the program mode may not be accessed while
the unit is communicating with a remote device.

3. SET CURRENT TIME & DATE

Note: The AHEAD/BACK buttons reset the seconds counter to zero as the button is released.

This feature can be used to accurately synchronize the Master Clock with other timekeeping
devices.
