4.8 Description and properties of the outputs and the input
4.8.1 Current output
All outputs are electrically isolated from the power supply.
Active mode: output range 0(4)...20 mA, load resistance R
L
≤ 550 Ω at I
max
≤ 22 mA,
U
int, nom
= 15 VDC.
Error signalling possible via current output (error current adjustable via software). For more
information refer to
Menu C, setup on page 46.
The functions of the current output can be adjusted via the menu:
Level mode
• Current output A: height height height height/depth depth depth depth of concentration 1 (fluff)
• Current output B: height height height height/depth depth depth depth of concentration 2 (sludge blanket)
Profile mode
• Current output A: The output range is calculated automatically by the OPTISYS SLM 2100
according to the parameters filled in the extended setup (dimensions).
• Current output B: The output range of current channel B must be define in the I/O menu of
the device.
Zone tracking mode
• Current output A: The output range is calculated automatically by the OPTISYS SLM 2100
according to the parameters filled in the extended setup (dimensions).
• Current output B: The output range of current channel B must be define in the I/O menu of
the device.
INFORMATION!
All cables must have a test voltage of min. 2 kV and an appropriate outer insulation (additional to
the insulation of the individual wire). The outer insulation should be removed 40 mm / 1.57". The
minimum cross section of the wires is 1.5 mm
2 / 0.0023 square inch and the maximum is
2.5 mm 2 / 0.0039 square inch.
INFORMATION!
In order to assure proper sealing of the cable feedthrough only cables with a minimum and
maximum diameter of 6-12 mm / 0.24-0.47 inch.
DANGER!
Never install or operate the device in potentially explosive areas, it might cause an explosion that
can result in fatal injuries.
INFORMATION!
For further information refer to the connection diagrams and the technical data table.
