Interfaces

→ RS232 Protocol → Binary

The binary protocol can be used to communicate with T-Guard™ Leak Detection
Sensor by software, written by a programmer. This method of communication is very
fast. It is, for example, the fastest way to read a leak rate from the T-Guard™ Leak
Detection Sensor.

Interfaces

→ RS232 Protocol → Printer Auto

After each measurement, the T-Guard™ Leak Detection Sensor sends data via
RS232.

Date, Time, Parameter set name, Measurement mode, Leak rate, Trigger 1, [Trigger
2].

Interfaces

→ Select PLC inputs

In this screen, you can select which functions can be called from the 6 inputs.

For default settings refer to section 4.6.2.

Interfaces

→ Select PLC-outputs

In this screen you can choose which information will be present on the 8 outputs.

For default settings refer to section 4.6.4.

Interfaces

→ Scaling Analog Output → Analog Output 1 .. 2

In this screen, you can set the upper limit and the volts/decade for the output on Pin
1 and 2.

Interfaces

→ Scaling Analog Output → Analog Output 3 .. 4

In this screen, you can set the upper limit and the volts/decade for the output on Pin
3 and 4.

Interfaces

→ Analog Output

In this screen you can choose which information will be present on the two analog
outputs.

Possible values: Off, Pressure, LR Mant, LR Exp, LR Lin, LR Log., Current Lin,
Current Log.
Default setting: 1..2: LR Exp, 3..4: LR Log.

Interfaces

→ Scaling Analog Output

In this screen, you can select how the voltage signal of the analog output has to be
interpreted, when "LR Log." or "Current Log." have been selected.
