General Specifications
Mode of Operation
DUB02 and PUB02 monitor
the TRMS value of their own
power supply.
Example 1
(no connection between ter-
minals Z1, Z2 or 8, 9 - Delay
ON alarm - N.E. relay)
The relay operates and the
yellow LED is ON as long as
the measured value is within
the upper and lower limits.
Function/Range/Level and Time Delay Setting
Adjust the input range setting
the DIP switches 5 and 6 as
shown on the right.
Select the desired function set-
ting the DIP switches 1 to 4 as
shown on the right.
To access the DIP switches
open the grey plastic cover as
shown on the right.

The relay releases after the
adjustable time delay when
the measured voltage exceeds
the upper set level or drops
below the lower set level.
The red LED flashes until the
delay time has expired or the
measured value falls off the
limits.

vided that the voltage has
dropped below the upper set
level (minus hysteresis) or
exceeded the lower set level
(plus hysteresis) for more than
the set delay time, the relay
operates when the intercon-
nections between terminals Z1,
Z2 or 8, 9 are interrupted. The
red LED flashes until the delay
time has expired or the mea-
sured value falls off the limits.
