Changing the default settings
The SIM-Q MKII can be reconfigured by means of four jumpers. (The original configuration is
marked on the label). The jumpers are placed on the PCB behind the rear cover, under the set
point potentiometer. See the drawing below for clarification.
DIP#1
= STANDARD/CUSTOM
DIP#2
= 500
μ
F/2000
μ
F
DIP#3
= 0 to 1 M
Ω
/0 to 10 M
Ω
DIP#4
= ND/NE
DIP#1
can be set to OFF (STANDARD), and the SIM-Q MKII will load its settings from a hard-
coded memory area. If it is set to ON (CUSTOM), the SIM-Q MKII will load its settings from a
configurable memory area that is used for custom settings and is set up by DEIF upon ordering.
DIP#2
can be set to either OFF (500
μ
F) or ON (2000
μ
F). The chosen setting will determine the
maximum leakage capacitance. Note that this will also change the measuring time. See the
chapter “Calculation of capacity within an application” for determination of the needed max.
capacity setting.
DIP#3
can be configured to OFF (measuring range 0 to 1 M
Ω
) with 22 k
Ω
on the scale centre, or
it can be set to ON (measuring range 0 to 10 M
Ω
) with 220 k
Ω
on the scale centre. Notice that a
change in measuring range also involves a change of scale.
DIP#4
settings will determine the SIM-Q MKII relay output. If it is set to OFF (ND), the output is
configured as a normally de-energised contact. If it is set to ON (NE), the output is configured as
a normally energised contact.
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.
Example:
•
Standard is selected (all jumpers are active).
•
Max. 500 μF leakage capacitor is selected.
•
1 M
Ω
is selected as measuring range.
•
ND is selected as relay function.
