instruction
The RESM-5 monitoring unit can be used as an
alternative to the RESM-4.
The steps necessary to convert from RESM-4 to
RESM-5 are described below.
These instructions provide only a brief overview of the
two monitoring units. If in doubt, please refer to the
latest version of the monitoring unit documentation,
which is always binding.
The electrical connections of the RESM-4 and RESM-5
monitoring units are NOT compatible (see wiring
diagrams).
The two models are also operated differently. Whereas
potentiometers are used to calibrate the RESM-4 and
set the alarm threshold, you do this on the RESM-5 with
a display and four keys.
Older RESM-1 monitoring units (for
temperature controllers in the "2xx" series)
cannot be converted using the RESM-5.
Preparation
1.
Select the unit
Select an RESM-5 with the same line voltage as the
old RESM-4 monitoring unit (115VAC, 230VAC, or
400VAC). The RESM-5 monitoring unit has the
following order numbers:
Line voltage:
115VAC
RESM-5/115VAC
Art. No. 885241
230VAC
RESM-5/230VAC
Art. No. 885242
400VAC
RESM-5/400VAC
Art. No. 885243
The line frequency is automatically detected
by the RESM-5 monitoring unit in the range
from 47 to 63Hz.
2.
Select the required components
Trouble-free operation of the RESM-5 monitoring
unit is only guaranteed in combination with the
following components:
- PEX-W2 or PEX-W3: Current transformer
- Alternatively: MSW-1 or MSW-2:
Monitoring current transformer
- LF-06480: Line filter 6A, 480VAC
In order to avoid malfunctions, the RESM-5 is
only allowed to be operated with the
specified components.
