Changing the default settings:
The SIM-2 can be reconfigured by means of four jumpers. (The original configuration is marked on
its label). The jumpers are placed on the PCB behind the rear cover, under the set point
potentiometer. See below drawing for clarification.
DIP#1 = STANDARD/CUSTOM
DIP#2 = 500 uF/2000 uF
DIP#3 = 0 to 1
MΩ/0
to 10
MΩ
DIP#4 = ND/NE
DIP#1
can be set to OFF (STANDARD) and the SIM-2 will load its settings from hard-coded
memory area. If set to ON (CUSTOM), the SIM-2 will load its settings from a configurable memory
area, used for custom settings, set up by DEIF when ordered.
DIP#2
can be set to either OFF (500 uF) or ON (2000 uF). The chosen setting will determine the
maximum leakage capacitance. Please note that this will also change the measuring time.
DIP#3
can be configured for OFF (measuring range 0 to 1
MΩ), with 22
kΩ on the scale c
entre or
set to ON (measuring range 0 to 10
MΩ), with 220
kΩ on the s
cale centre. Please notice that a
change in measuring range also involves a change of scale.
DIP#4
settings will determine the SIM-2 relay output. If set to OFF (ND), the output will be
configured as a normally de-energised contact. If set to ON (NE), the output will be configured as a
normally energised contact.

IMPORTANT - Use electrostatic discharge protection!
Sufficient care must be taken to protect the PCB against static discharges during the configuration. Once
the unit is installed and connected, these precautions are no longer necessary.
