Pushbutton functionality during operating mode. FUNC = o when the instrument is in "normal

display mode"

1)with a brief pressure (<3s) it starts the parameter modification procedure.

2)with a pressure within 3s to 10s it changes the indication on the lower display (see "display function").

3)with a pressure longer than 10s it enables the lamp test (see "Lamp Test" paragraph).

oDuring parameter modification, it allows to memorize the new value of the selected parameter and go to the next parameter (increasing order).

MAN =

pressed for more than 1 s, it allows to

 

enable or disable the manual function

 

and, during parameter modification,

 

to scroll back the parameters without

 

memorizing the new setting.

s= o During parameter modification, it allows to increase the value of the selected parameter.

oDuring MANUAL mode, it allows to increase the output value.

t= o During parameter modification, it allows to decrease the value of the selected parameter.

oDuring MANUAL mode, it allows to decrease the output value.

s+MAN = During parameter modification they allow to jump to the maximum programmable value.

t+MAN = During parameter modification they allow to jump to the minimum programmable value.

NOTE: a 10 or 30 seconds time out (see P 36) can be selected for parameter modification during run time mode.

If, during operative parameter modification, no pushbutton is pressed for more than 10 (30) seconds, the instrument goes automatically to the “normal display mode” and the eventual modification of the last parameter will be lost.

ENABLE/DISABLE THE CONTROL OUTPUT When the instrument is in "normal display mode", by keeping depressed for more than 5 s s and FUNC pushbuttons, it is possible to disable the control outputs. In this open loop mode the device will function as an indicator, the lower display will show the word OFF and all control outputs will also be in the OFF state (the output is also conditioned by P18 and P20 parameters).

When the control outputs are disabled the alarms are also in non alarm condition.

The alarms output conditions depend on the alarm action type (see P24-P26).

Depress for more than 5 s s and FUNC pushbuttons to restore the control status.

The alarm stand-by function, if configured, will be activated as if it was at power up.

If a power down occures when the control output is disabled, at instrument power up the control output will be automatically disabled.

SP - SP2 SELECTION

It is possible to select the operating set point (SP or SP2) only by an external contact (terminals 14 and 15).

By setting P43, it is possible to display the final or the operative set point during a ramp execution.
