8.4.- NOTES
The HOURS, MINUTES & SECONDS inputs are for contact closure to GND, and are pulled up to the auxiliary 15
volt rail through 4.7 KΩ.
The STOP, START and RESET inputs are normally configured to be pulled up to the auxiliary 15 volt rail through
1 KΩ, but may be internally jumpered to be pulled to GND through 1 KΩ, or pulled to GND through a high resistance
of 100 kΩ.
Debouncing for 200 mS time constant is normally incorporated on the three control inputs, but may be disabled by
removing internal jumpers.
Vexc is the Excitation Voltage for sensors supplied by the instrument (pins 1, 2 & 9).
The connections to Serial A, Serial B and GND are for the RS422 data output.
Run time uncertainty
The control inputs are sensed eight times per second, but the actual run time clock is incremented or decremented
in synchronism with the built in real time clock once per second.
This means that each start/stop condition may be inaccurate by up to one second.

8.5.- EXCITATION VOLTAGE FOR SENSORS
The unit supplies the Excitation Voltage for sensors, through control lines connector.
If the current required for the sensors installed is more than 100 mA then do not use this terminal. Install other external
power supply. See paragraph 5 for technical specifications
9.- POWER-UP AND OPERATION
9.1.- REAL TIME CLOCK
At power-up, the unit displays the message MAStEr for 6 decade version or MASt for 4 decade version and will
start to operate.
If a failure occurs then will display the messages CHIP or SET.
The message CHIP means that the failure is the internal
hardware and the message SET means that the data stored in
the memory is damaged and it must be restored.
The restore data operation can be made while the instrument
is in normal operation or while the error message SET is on the
display using the control lines HOURS, MINUTES & SEC-
ONDS.

Reaction to the control lines is once per second.
To obtain a complete reset in a real time clock configuration, connect terminals 14 & 13 to GND simultaneously.
The display can be switched in to Run Time Clock mode by inputting an active signal on to any of the three control
lines START, STOP or RESET.
9.2.- RUN TIME CLOCK
At power-up, the unit displays the message MAStEr for 6 decade version or MASt for 4 decade version and will

depending upon the internal configuration of the unit as shown in paragraph 10.2.4.
The factory default settings are for contact closures to GND for all three inputs. Reaction to the control lines is once
per second.
Note on the 4 decade clock the run time clock may be either for hours and minutes or for minutes and seconds. During
run time hours and minutes, the colon will flash on and off every second while the clock is running to indicate the
clock is running.
9.2.1.- UP / DOWN TIMING
The run time clock has two basic modes of operation; a run up clock or a run down clock. These modes are
controlled by a internal DIP switch (See DIP SWITCH CONFIGURATION in paragraph 10.2.3).
Run up clock
Reset will clear the clock to zero. When the alarm point is reached, if the alarm is enabled, the clock will stop
and the whole display will flash and the alarm output will be activated, until the clock is reset. If the alarm is
disabled, the clock will run up to 99 minutes 59 seconds (or 99 hours 59 minutes) and then roll over zero.
Run down clock
Reset will preset the clock to the alarm point. When zero is reached, if the alarm is enabled, the clock will stop
and the whole display will flash and the alarm output will be activated, until the clock is reset. If the alarm is
disabled, the clock will run down to zero and then underflow to 99 : 59.

9.3.- RUN TIME ALARM SETTING
The alarm is a 4 decade alarm only. On the 6 decade clock, the alarm setting is for hours and minutes only and
on the 4 decade clock the alarm point can be for either hours and minutes or minutes and seconds.
Displaying or setting of the alarm point can only be done when the unit is displaying the run time and is not
running.
The same three contact inputs are used for setting the alarm point and for adjusting the real time clock, but their
functions are different.
To display the alarm set point, hold the SECONDS input (pin 13) to GND. Once the alarm point is displayed, the
value can be changed by contact closure between GND and the following terminals :
Seconds ........................... view/adjust alarm point ( hold to GND).
Minutes ............................ increment seconds ( or minutes).
Hours ............................... increment minutes ( or hours).
Hours and Minutes .......... together reset alarm to zero
9.4.- SERIAL DATA OUTPUT
The unit incorporates and RS422 level serial ASCII output to allow master/slave clock setups in conjunction with
serial ASCII remote displays.
Details of the serial output to be found in paragraph 5.
Note the line should be terminated to prevent noise pickup if the clock is not transmitting data.
10.- CONFIGURATION
10.1.- POWER SELECTION
See the rear label for power requirements. Power supply selection must be done by suitable qualified
personnel or by the local distributor. Contact factory or your local distributor for instructions.
10.2.- INSTRUMENT CONFIGURATION
To change the instrument configuration, the rear panel of the instrument needs only to be removed to gain
access to the internal DIP switches and jumpers located on the control board.
Be sure that the instrument is disconnected from any power supply before removing the rear panel.
