HOW TO DISMANTLE SYSTEM 2200

The back panel of the module is detached from the housing by way of a screw-
driver as shown in picture 1.
On a module with knobs, these may have to be removed before the PCB can be
taken out as shown in picture 2.
After this, the back panel can be pulled out together with the PCB, but please
notice the position of the PCB as there is a number of different positions in the
house. Do not pull the wires unnecessarily, instead pull the PCB, see picture 3.
Switches and jumpers can now be moved.
When assembling the back plate and housing, please make sure no wires are
stuck.

and replacement of jumpers.

R/I TRANSMITTER 2202
Input for Pt100, Ni100 or Ohm
Sensor cable compensation
Linearised analogue output
24 VDC or universally supplied
Individual 0 and 100% adjustment
DIN rail mounting on a standard 11-pole relay socket

APPLICATION:

Electronic temperature measurement with a Pt100...Pt1000 or a Ni100...Ni1000
sensor. • Conversion of a linear resistance change to a standard analogue cur-
rent / voltage signal from e.g. valves or linear movements with attached potenti-
ometer. • As signal simulator via externally mounted 10-turn potentiometer.
• Suitable in applications with potentiometers that are not fully utilised as the 0
and 100% adjustments on the front can be adjusted individually without interacting.

TECHNICAL CHARACTERISTICS:

GENERAL:
The unit is built around a microprocessor core with an efficient program operation.
The supply voltage may be ordered to 24 VDC or with a universal supply of
24...230 VAC and 24...250 VDC with galvanic isolation between supply and input /
output ground. The adjustment range for the 0 and 100% trimmers has a stan-
dard set-up for ±2.5% of span, but the module may be ordered with an adjust-
ment range of up to ±25%. The sensor connexion is always a 3-wire connexion
with cable compensation for up to 10 Ω in each wire. If a 2-wire connexion is re-
quested pin 7 and 6 must be short-circuited in the socket (no cable compensation).

INPUT:

Pt100 temperature input according to the norm IEC 751 within the range
-200...+850°C. Ni100 temperature input according to the norm DIN 43760 within
the range -50...+250°C. Linear resistance input within the range 0...10 kΩ. The
measurement range should be specified when placing the order, e.g. 0...150°C.
The min. span is 50°C for the RTD input; for linear resistance the min. span is 30
Ω. The RTD input can be delivered as multiples of the main type
( e.g. Pt100 x 10 = Pt1000 ). The input can be reversed so that 0% e.g. is 150°C
and 100% is 0°C.
