2.1 Preface
Please read these Operating Instructions before commissioning the
instrument. Keep the manual in a place that is accessible to all users at all
times.
Please assist us to improve these operating instructions, where necessary.
Your suggestions will be appreciated.
Phone [phone]
Fax [phone]
All necessary settings are described in this manual. However, if any
difficulties should still arise during start-up, please do not carry out
any unauthorized manipulations. You could endanger your rights
under the instrument warranty!
Please contact the nearest subsidiary or the main factory in such a
case.
Caution
A sudden failure of a measuring cell may lead to excessive or
insufficient dosing of oxygen. This may harm living creatures (fish
in ponds or micro-organisms in wastewater-treatment plants).
Appropriate precautionary measures must therefore be taken in
such a case.

Basic version, type 202610/80...
- Two-wire transmitter JUMO dTRANS O2 01
- 8 m attached cable
- Terminal/operating unit with button for calibration
The basic version is designed for direct connection to a PLC or a recorder. The
calibration function can be initiated locally. An optional setup program is
available for configuring the transmitter. The two-wire transmitter is powered
by a separate power supply (optional), e.g. JUMO TN-22, see Data Sheet

Basic version, type 202610/80...
The JUMO dTRANS Az 01 (Jumo Data Sheet 20.2550), bezel size 96 x 48 is a
suitable indicator/controller for the basic version. This instrument is
recommended where there is no requirement for a direct connection to a PLC
or recorder. The JUMO dTRANS Az 01 can also provide the 18 V DC supply
necessary for the two-wire transmitter. See Data Sheet 20.2550 for further
details.

Standard version, type 202610/81...
As for the basic version, but with an operating unit (instead of the terminal box)
featuring a display and additional operating keys. The two-wire transmitter and
the operating unit are powered by a separate power supply (optional), e.g.
JUMO TN-22, see Data Sheet 95.6024. A further power supply (e.g. JUMO
TN-22) is required for the supply of the additional (optional) two-wire
transmitter for temperature. The instrument is operated from the membrane
keypad and operator prompting in plain text ensures that operation is
straightforward. The instrument is configured via the operating unit.

Full (maximum) version, type 202610/82...
As for the standard version (see above). The operating unit has its own power
supply to power the two-wire transmitters for oxygen and temperature. The
output signal is in each case a 4 — 20 mA standard signal. In addition, this
version comes with two freely programmable relays for alarm generation and
limit monitoring. The display features backlighting.
