AL_2

Programming alarms consists in setting their work modes and values 

of threshold temperatures. 

Enter the programming mode by depressing „

p

” for approx. three 

seconds. 

Using  „

u

” select from the menu position „

AL_1

” or „

AL_2

”, confirm 

by „

tu

”.

4.1.

Setting the alarm mode

In the alarm programming mode using „

u

” select „

TAL

” position.

The auxiliary display will show the current alarm mode. To change 

the mode depress „

tu

” (the digit on the auxiliary display starts 

blinking).

Using „

p

” set the required alarm mode. 

!

Mode 

0

  alarm is off,

!

Mode 

1

  alarm comes on when the current temperature exceeds the 

first alarm threshold, 

!

Mode 

2

  alarm comes on when the current temperature drops below 

the first alarm threshold,

!

Mode 

3

  alarm comes on when the current temperature exceeds the 

first alarm threshold, and at the same time is lower than the second 

alarm threshold.

!

Mode 

4

  alarm comes on when the current temperature drops below 

the first alarm threshold or exceeds the second alarm threshold.

!

Mode 

5

  alarm comes on when the current temperature exceeds the 

second alarm threshold, and comes off when temperature drops below 

the first alarm threshold (hysteresis). If a power outage appears in this 

mode the meter memorises states of relays and the last temperature, 

This makes possible correct alarm operation after re-powering.

Alarm modes are presented in a graphical form on page 22.
