RESM-4/RESM-5 Replacement
Installation and startup
Installation and startup may only be
performed by technically trained, skilled
persons who are familiar with the associated risks
and warranty provisions.
Please also refer to the relevant product
documentation as well as to the ROPEX
Application Report.
The information provided here offers no more than a
brief overview. If in doubt, please refer to the latest
version of the product documentation, which is always
binding (
see also section 1 of the RESM-5
documentation, "Safety and warning notes").
Proceed as follows to replace the RESM-4 monitoring
unit and install / start up the RESM-5:
1. Switch off the line voltage and verify that the circuit
is de-energized.
2. Remove the old RESM-4 monitoring unit.
3. The supply voltage specified on the nameplate of
the RESM-5 monitoring unit must be identical to the
line voltage that is present in the plant or machine.
The line frequency is automatically detected by the
controller in the range from 47 to 63Hz.
The RESM-4 has coding switches on the
housing for setting the secondary voltage
and current ranges.
The RESM-5 has been provided with an
AUTORANGE function instead of these switches.
The voltage and current ranges are automatically
set when you run AUTOCAL.
Old setting ranges on the RESM-4:
AUTORANGE function on the RESM-5:
The RESM-5 monitoring unit has no coding switches on
the housing. The voltage (0.4…120V) and current
(30…500A) ranges are automatically set when you run
the AUTOCAL function. Heed the information provided
in the ROPEX Application Report in order to avoid
malfunctions.
4. The number of times the wire is laid through the
PEX-W2/-3 or MSW-1/-2 current transformer for the
RESM-5 must be the same as for the RESISTRON
temperature controller. Heed the information
provided in the ROPEX Application Report in order
to avoid malfunctions.
5. Install the RESM-5 monitoring unit in place of the
RESM-4. The terminals of the two devices are
NOT
compatible (see wiring diagrams).
6. Make sure no START signal is applied to the
RESISTRON temperature controller.
7. Switch on the line voltage.
8. A power-up message appears on the display when
you switch on the monitoring unit to indicate that it is
being powered up correctly.
9. One of the following states then appears:
