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 starting can be programmatically
disabled (Chapter V).

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 - 

not lit.

The status of the outputs is indicated by the six dots on the display - a flashing dot

means an active output; off point - inactive.
