Connecting And Start - Magnet-physik EF 14 Operating Instructions Manual

Electronic Fluxmeter
for various in- and outputs and the line power supply socket with fuse and main switch are
installed.
Details on the pin configuration of the sockets are given in chapter 7.
Measuring coil connection: the 15-pole socket for the measuring coil connection is located on
the front panel. The coil connecting plug must be lined up with the socket and carefully bound
to prevent the contacts being bent. It should be fastened using the two screws. A tight
connection prevents the connector being pulled out unintentionally and reduces disturbances by
drift.
The connector can be plugged and unplugged without switching off the instrument. However, it
should not be unplugged immediately after it has been plugged in (within about 2 seconds).
On the rear panel of the instrument you can find a pair of pole clamps, where coils with bunch
or banana plugs can be connected or wires can be clamped.
Important!
Only one measuring coil must be connected at one time, either to the socket
on the front panel or to the clamps on the rear panel. If both connections are
used at the same time, this will cause faulty measurements.
RS 232 plug: The 9 pin Sub-D plug has the connections for RS 232 interface. The EF 14 can be
connected to a computer using a so-called Null-Modem-Cable.
I/O socket: This 25 pole socket has multiple functions. It contains the relay output for the limit
function, the analog output and digital control lines.
Power supply element: The power supply socket with fuse and On/Off switch is the input for
the AC power supply. The power supply connection cable is attached to the power supply
socket.

2.4 Connecting and Start

The following procedure describes how the device is put into operation. It serves to check the
basic functions of the device before being used for measurements.
Caution!
Check that the power line has the correct voltage before you connect the
device to the system. The device can be damaged if connected to the wrong
voltage! The EF 14 works with 90-250 V alternating voltage.
1. Make sure that the ON/OFF switch is at OFF (0).
2. Connect the coil plug to the input socket. Use the screws to fix the plug to the instrument.
Alternatively you can use the pole clamps on the rear panel. Always only connect one coil.
3. Make sure all other necessary connections have been made before switching on the device
e.g. interface or analog output.
