III. DESIGNATION
The MS8326 device is organized as two timer blocks, operating independently or
interconnected. Both timers can work in the modes:999 min; 999 s; 999 s.10-1 ;999 s.10-2.
Each timer counts two times - time tLo, and time tHi, and for each of them the user sets a
group of outputs to be active.When an output is connected to both timer modules, "OR"
logic is valid. Timers can be started from an external input, from a key on the keyboard or
from the other timer. It is provided to remember the current state in case of power failure
and the possibility for automatic or non continuation of the execution. Independent RESET
inputs are taken out for each timer, as well as common for both RESET modules from the
keyboard.

IV. OPERATING GUIDE
When the supply voltage is applied, the timers are ready for operation, and the current
values before the power supply is stopped are displayed. In case these are unfinished jobs,
the corresponding LED on the front panel flashes, and if the timer was not active when the
power supply fails, the display shows the setting tLo, the LEDs for this timer are off. There
are two ways to start the timer:
Hold down
the button for
the left
TIMER 1
1. Starts the timer from the value shown on the
display. This completes the job if it did not
complete when the power was turned off.
Otherwise, holding down any of these buttons
starts the corresponding timer from the beginning.
This way of starti g ca be programmatically
disabled (Chapter V).
for the right
TIMER2
If necessary, the RESET key combination can be selected before
starting - the times tLo for both timers are loaded. A separate RESET
is possible via the corresponding external inputs.
2. When an active level is applied to one of the Start inputs, the corresponding
timer loads time tLo and is activated.
After starting, the timer starts to decrease its current value until it reaches 0. During
time tLo the associated group of outputs is active. After its expiration, the time tHi is
charged and its corresponding group of outputs is activated. When tHi is over, tLo is
charged and, depending on the operating mode, it is switched to start or restart. The current
timer status is indicated by two LEDs on the front panel.
The timer is not active. The tLo setpoint is loaded - ot lit.
Time tLo is running out - the gree LED is lit.
Time tHi is running out - the red LED is lit.
Pause after power on in stage tLo - gree LED flashes
Pause after power on in stage tHi - red LED flashes
The status of the outputs is indicated by the six dots on the display - a flashing dot
means an active output; off point - inactive.

REVIEW AND EDITING OF SETPOINTS (SP)
Setpoints of timers can be viewed by pressing and holding the buttons as shown:
tLo tHi
The button combinations shown in the table are used to change the SP:
SP
of
timers
tLo
(the buttons are pressed with priority on the left)
tHi (tHi>0)
(the buttons are pressed with priority on the right)
Timer 1
Timer 2
The value of the selected SP is displayed (flashing). With the buttons below the flashing
number, it is edited. Five seconds after the last button is pressed, the new SP is saved and
exits the edit mode
The curre tly active task is updated whe it is reloaded. (Example: While time tLo is
ru i g o timer 1, this setpoi t is corrected. There is o immediate cha ge, o ly after a
restart the ew setpoi t tLo is loaded.)

RESET ON BOTH TIMERS FROM THE KEYBOARD
RESET can be applied to both timers by pressing buttons simultaneously:
On display: [- - -] [- - -]
V. EDIT OF SETTINGS
In this mode, the timer operation mode, start mode and internal restart permission are set.
Entering this mode is done by pressing and holding for more than 5 seconds
simultaneously on the buttons
The following symbols appear on the display:
ABc
By butto below the symbol 'A' e ters the setti g of Timer 1 parameters .
By butto below the symbol 'В' e ters the setti g of Timer 2parameters .
By butto below the symbol 'с' exits the setti g mode.
By butto below the symbol '' e ters the me u for co figuri g the outputs.
When one of the two timers is selected, the following symbols appear on the display:
OPc
By button below the symbol О the output type of the respective timer is set.
By button below the symbol the start mode for the respective timer is set.
By button below the symbol Р the reporting format of the respective timer is set.
By button below the symbol с exits to the above mode.
When editing the corresponding values, the display shows the following:

VI. RECOMMENDATION AGAINST EMI (Electromag etic I terfere ce)
Recommendations for use of connecting wires
✔For longer distances for lines subjected to electromagnetic interference, it is desirable
to use a twisted pair wire.
✔For better noise protection, a shielded cable may be used, which must be grounded at
only one end.
✔Wires that carry a similar type of signals can be packed together, but if the signals are
different, the wires must be separated to prevent electromagnetic interaction.
✔When there have to be crossed wires with different signal types this must be done at an
angle of 90 degrees and a long distance.
✔Wires, which carry weak signals and wires connecting the sensors to the controller
must not be near contactors, motors, generators, radios and wires, which carry large
currents.
