9. Connecting the MT-2
Follow the connections diagrams fig. MT-2.1 and MT-2.2 and connect
the minitimer MT-2 as follows:
X1-1
device
(polarized device "+")
X1-2
device
(polarized device "-")
X2-1
switching input
X2-2 transformer
(with direct voltage "+")
X2-3
transformer / earth
(with direct voltage "
^
")
In order to trigger the minitimer MT-2 you have to connect the
switching input (connection X2-1) to earth (connection X2-3), e.g. with
a switch. After the set delay time the connected device will be switched
on. Approx. 1 second after interrupting the earth connection between
X2-1 and X2-3, the device will be switched off.
Setting the time delay
Set the desired delay time at the trimm pot R7. Please note: In case the
time passing between making and interrupting the earth connection
between X2-1 and X2-3 is shorter than the preset delay time, the
connected device stays off.
Connecting a relay
In order to switch a device with more than 100 mA power consumption or
to switch off a device you have to connect the device via a relay (5 V) and
an protective diode (e.g. 1N4148) as anti-surge diode. When operating
the module without an anti-surge diode it will be destroyed after
several switchings.
