Sniffer line SL200 or test chamber
TC1000 (ACCESSORIES)
The connection ACCESSORIES serves for connecting the sniffer line SL200 or the
test chamber TC1000.
External Pressure gauge
If the Modul1000 is used in Commander mode, an additional pressure gauge has to
be connected to PRESSURE GAUGE. Connect the pressure gauge as follows with
the 8-pin Phoenix-plug "PRESSURE GAUGE".
Notice: The pressure transmitters to be connected can be supplied via the contacts
1 and 2 of the Modul1000.
If they are supplied by external power supply units, ensure that the contacts
4 and 6 may only have a maximal potential of ±4V compared to contact 2.
Otherwise it could be damaged.
Notice: The sensor is adjusted correctly, when the zero point and the full-scale
deflection comply with the output characteristic.
The Modul1000 can process measured current or voltage values. When delivered,
the Input 1 is configured for current measurement 4... 20 mA, Input 2 for voltage
measurement 0... 10 V.
To change the configuration of the input of the pressure gauge, the respective jumper
on the interface card in Modul1000 has to be placed onto another position. To do
that, open the device.
The jumpers are located on the interface board and are accessible after opening the
cover.
By changing the position of the jumper on the connector XP5, the setting of the Input
1 can be changed. For a current signal, Pin 1 and Pin 2 of XP5 are connected, for a
voltage signal, connect Pin 2 and 3.
By changing the jumper position on the connector XP4, the setting of the Input 2 will
be changed. However, this input is not supported in the current software.

5 Input 2 (is not supported by the current software)
6 GND to input 2
STOP Danger
Danger of fatal injuries due to electric shock!
First, disconnect the leak test device from the power supply network and then
remove the housing.
