100 MM RECORDER USER GUIDE
100 mm. RECORDER USER GUIDE
1 INTRODUCTION
The main part of this manual describes recorders fitted with membrane switches on each side of the display unit. An-
nex A contains information on older models, (those with status levels prior to L19 (Multi-point recorders) or L22
(Continuous-trace recorders)). The status level appears as the last two or three character section of the recorder serial
number.
The recorder comes in two versions - a continuous-trace recorder with up to four pens and a multipoint recorder giv-
ing up to six traces on the chart. Chart annotation is standard with the multipoint version, but is an optional extra
(specified at time of order) with the continuous trace recorder. Annotating recorders print power-on and alarm on/off
messages, time and date. Scales and channel tags are also printed on the chart to simplify trace interpretation.
Designed to fit a DIN cutout (138 x 138 mm) the recorders feature an exceptionally small back of panel dimension of
220 mm. (no terminal cover) or 236 mm (with cover).
ANNOTATOR BATTERIES
When the batteries associated with the recorders are fully charged, they will maintain the real-time clock for approxi-
mately one month (depending on temperature etc.), without power applied to the recorder. The batteries are
uncharged when despatched from the factory, and it takes approximately 175 hrs to charge them fully. Should power
be removed from the recorder before this, the retention time will be reduced accordingly.
1.1 Unpacking the recorder
The recorder is despatched in a special pack designed to give adequate protection during transit. Should the outer box
show signs of damage, it should be opened immediately and the recorder examined. If there is evidence of damage,
the instrument should not be operated and the local representative contacted for instructions. After the recorder has
been removed from its packing, the packing should be examined to ensure that all accessories and documentation
have been removed. Once the recorder has been installed, any internal packing should be removed, and stored with
the external packing, against future transport requirements.
2 INSTALLATION
2.1 MECHANICAL INSTALLATION
Figure 2.1 gives installation details.
The recorder is inserted through the panel aperture from the front of the panel. With the weight of the recorder sup-
ported, the panel clamps are inserted into one pair of the rectangular apertures (either at the top and bottom or at the
right and left sides) of the recorder. The jacking screws are then be tightened sufficiently to clamp the recorder into
position. EXCESS FORCE SHOULD NOT BE USED IN TIGHTENING THESE SCREWS.
