4.4Voltage supply

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

DANGER!

GB

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 difficulty.

Manual Firmware

2.1.01.32

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 off.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 different 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).

7.3 Interface configuration

Press the MENU button and press the/button until the SETTINGS submenu item appears and confirm with SELECT.In the submenu, go to the item RS-232/USB with the/button and confirm with SELECT.The following settings can be made:

■■ACTIVE: Selection of whether a serial interface will be used and which serial interface (USB, RS-232)

■■BAUD: Selection of the baud rate (1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 56000, 57600)
