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 centre or

set to ON (measuring range 0 to 10 MΩ), with 220 kΩ on the scale 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.

Page 2 Measuring circuit: Connect PE to ground and P to a phase (if it is a 3-phased network – connect to any of the phases). Warning: If a high-voltage “MEGGER” is used, the SIM-2 must be disconnected at terminal “P” before testing is carried out. Ignoring this may result in damage to the SIM-2. Adjustment of the set point When the selector on the front is placed in Test mode, the meter indication shows the set point setting directly.
