Deif SIM-Q MKII Quick Start Manual

Quick start guide
SIM-Q MKII insulation monitor
Installation
1. Make sure the SIM-Q MKII is correctly configured for the specific application.
2. For the auxiliary supply, connect the terminals to the correct voltage. See the label on the SIM-Q MKII.
3. Connect PE to ground and P to a phase. If it is a 3-phase network, then you can connect any of the phases to
P.
The recommended fuse size is maximum 2 A.
High-voltage MEGGER
If a high-voltage MEGGER is used, the SIM-Q MKII must be disconnect at terminal P before tests are
done. Failure to do so may result in damage to the SIM-Q MKII.
Adjustment of the set point
1. Turn the knob on the front of the display to TEST. The SIM-Q MKII is now in test mode.
2. The actual set point is shown on the display.
3. Go the rear of the SIM-Q MKII to adjust the set point.
During the first 10 seconds after you turn on the SIM-Q MKII, the meter pointer shows the actual set point setting
and activates its relay.

Default settings
Use the four jumpers on the PCB to configure the relay and change the default settings. Remove the rear cover to
access the jumpers. The jumpers are under the set pointer potentiometer.
Configure the DIP switches
• DIP #1: You can set DIP #1 to OFF (Standard) or ON (Custom). If you set the switch to OFF, the SIM-Q MKII
loads the settings from a hard-coded memory area. If set to ON, the settings are loaded from a configurable
memory area, which is configured by DEIF.
• DIP #2: You can set DIP #2 to OFF (500μF) or ON (2000 μF). The switch is used to configure the maximum
leakage capacitance.
• DIP #3: You can set DIP #3 to OFF (measuring range 0 to 1 MΩ) with 22 kΩ on the scale centre, or ON
(measuring range 0 to 10 MΩ) with 220 kΩ on the scale centre. *
• DIP #4: Use DIP #4 to configure the relay output. If you set the switch to OFF (ND), the output is a normally
de-energised contact. If you set the switch to ON (NE), the output is a normally energised contact.
NOTE * A change of scale is necessary when you change the measuring range.
Electrostatic discharge protection
You must protect the PCB against static discharges during configuration. When the SIM-Q MKII is
installed and connected, these precautions are no longer necessary.
