Setting; Technical Data - DOLD MINITIMER MK 9962N Mode D'emploi

Notes
Remote potentiometer
With the variant MK 9962N.82/300 the time setting can also be made
via remote potentiometer of 10 kOhms. It is connected to the terminals
Z1-Z2. The corresponding potentiometer on the relay has to be set to min. If
no remote potentiometer is required the terminals Z1-Z2 have to be linked.
The wires to the remote potentiometers should be installed separately
from the lines with mains voltage. If this is not possible, a screened cable
is recommendet where the shield is connected to Z2.
To terminals Z1 and Z2 no external voltage must be connected, as the unit
might be damaged.
Control input B1
The unit needs a continuously connected auxiliary supply on A1-A2. The
timing is controlled via input B1. The control unit B1 (+ with DC) has to be
supplied with voltage against A2. The control signal could be the same as
the auxiliary/control voltage of A1 or any other voltage between 12 and
240 V AC or DC. Operating a parallel load (e.g. a contactor) between B1
and A2 is also allowed.
Time interruption and time addition with X2 - X3
The time delay can be interrupted during timing by bridging the terminals
X2 - X3. By opening the bridge the time continues (time addition).
While X2 and X3 are bridged the control input is disabled and the yellow LED
remains in the state it had at stop. No external voltage must be connected
to X2 and X3 as the unit may be damaged.
