4.4 Voltage supply

The low-pressure controller is factory set for connection to a voltage supply of DC 24 V.
The power supply connector is located on the rear panel.

DANGER!

Electric shock hazard! Before removing the fuse, the power supply must
be removed from the plug.
Operation using a defective power supply unit (e.g. short circuit from the
mains voltage to the output voltage) can result in life-threatening voltag­es at the instrument!

Only the original power supply unit included in initial delivery (Mascot
model 9926) should be used.

1. Design the wiring particularly carefully when connecting to other devices. Under

certain circumstances, internal connections in third-party devices (e.g. GND connect­ed to the ground) can lead to impermissible voltages that could compromise or even
destroy the function of the device itself or a device connected to it.

2. The mains plug must always be plugged in to a mains socket and be accessible, so

that one can always remove it from the mains socket without diculty.

With this button the SETUP menu can be accessed, and there the
settings for each operating mode can be made. When the CTRL mode
is used, you will nd that the device is left in VENT mode on leaving the

SETUP menu.

4.5.3 LEAK button

With the LEAK button, a device connected to the controller can be
tested for leaks. (This feature is only available in CONTROL mode.)

4.5.4 ZERO button

Button for manually correcting the zero point of the integrated sensor.
External inuences such as temperature, pressure, mounting position or
surroundings, can alter the zero point of the instrument, i.e. the display
when the pressure ports are open. During zero adjustment, the device
automatically detects these changes and corrects them in the current
pressure display. The zero point adjustment requires a change of the
internal valves, which is not possible without loss of pressure.
(If this should interfere with the application, the automatic zero point
adjustment can be switched o.)

2.1.0 1.32

There is a possibility to control and monitor the controller via a PC over a serial interface
(USB or RS-232). In control, measure and automatic modes a cyclic output of the current
instrument status can be switched on and o. The output interval is 1 second.

7.1 USB interface

The PC provides a virtual COM port over the USB interface. The control of the instrument
is therefore no dierent from the control via the RS-232.

7.2 RS-232 Interface

To connect, the RxD, TxD and GND lines are required. The connection is made with an
in-line serial cable (1:1, male/female).
