Instructions
The RESISTRON temperature controller RES-403 can
be used as an alternative to the RES-203-0-x
controller.
The steps that are necessary to convert from
RES-203-0-x (standard model without modifications) to
RES-403 are described below.
These instructions only provide a brief overview of the
two controllers. If in doubt, please refer to the latest
version of the controller documentation, which is
always binding.
The convertion from controller types RES-203-1-x is
not described here. Please contact ROPEX for further
informations.
Replacement steps
1. Select the controller
Select an RES-403 with the same line voltage as the
existing RES-203-0-x controller (115VAC, 230VAC
or 400VAC). The RES-403 controller has the
following order numbers:
Line voltage: 115VAC ª RES-403/115VAC
Art. No. 740301
230VAC ª RES-403/230VAC
Art. No. 740302
400VAC ª RES-403/400VAC
Art. No. 740303
The temperature range (300°C/500°C) is adjusted
by a rotary coding switch on the RES-403.
2. Select the required components
Trouble-free operation of the RES-403 controller is
only guaranteed in combination with the following
components:
- PEX-W2: Current transformer
- PD-3: Potentiometer with digital dial, 0…300°C
alternative:
PD-5: Potentiometer with digital dial, 0…500°C
- LF-06480: Line filter 6A, 480VAC
The RES-403 controller must always be used
together with the PEX-W2 current
transformer and the PD-3 or PD-5 potentiometer.
Other transformers or potentiometers may cause
the equipment to malfunction. If these components
have already been used with the RES-203, they can
continue to be used with the new controller.
