REGULATIONS AND GENERAL
FEATURES (fig. 4,5)
SP1
Max set point, adjustable by means of
screwdriver. The scale is divided in 10
parts. The value of each part
corresponds to 1/10 of the full scale FS.
SP2
Set point adjustable by screwdriver as
max or min power set point. The scale is
divided in 10 parts. The value of each
part corresponds to 1/10 of the full scale
FS.
When the SLIDER m/M-DS2 is “UP”
(Fig. 1) the SP2 is MAX set point.
When the SLIDER is “DOWN” the SP2
is min. set point (in that case, with the
slider A/Ⱥ the condition V=0 is selected
as “ALARM” (UP POSITION) or “NO
ALARM” (DOWN POSITION), fig. 5/1
and 5/2).
The minimum value which can be set is
1/10 of the full scale.
TC
Initial timer adjustable by screwdriver on
the front (0,1÷10 sec) excluding set
point triggerings at the start, for covering
an eventual initial spike. It covers both
the sets points.
The timer is activated when the voltage
overcomes the internal set point Vm
(Vm corresponds to 1/10 of the range.
Ex.: VFS=100V, Vm=10V).
T1
Timer delaying the internal relay
associated to the set point SP1 (0,1÷10
sec).
T2
Timer like T1 for the set point SP2.
VISUALIZATIONS
ON GREEN LED supply on
A1 RED LED set point SP1 alarm
A2 RED LED set point SP2 alarm
In case of one SET POINT overcoming,
during T1, T2, TC, the led A1 (and/or
A2) flashes quickly, at the end of T1 (or
T2) the led A1 (and/or A2) remainslighted, with FIXED LIGHT, if the
overcoming continues to be present.
The led A1 (or A2) flashes at LOW
FREQUENCY, if the memory started
and the overcoming stopped.
MODE OF OPERATION
When the voltage is applied at the input,
the timer TC bypasses the eventual
spike. After the end of TC, each set
point triggers after the delay time T1 and
T2. INPUTS
Voltage pins: 19-17.
Input Resistance = 10 kW/V.
