Incorporating the reset board
The reset board can be used as an option for the TITANUS MICRO·SENS
®
.
The reset board is mounted in an additional housing. If several TITANUS
MICRO·SENS
®
are connected to a detection line, then the reset board is
only connected into the detection line after the last TITANUS
MI-
CRO·SENS
®
. The electrical connection to the reset board is as per the
switching plan (see Figure “Fitting the rest board into the TITANUS
MI-
CRO·SENS
®
additional housing“).
NOTICE
The reset board can only be used if the idling current on the detection line
is between 5 mA and 50 mA and the detection line terminal has an ohmic
resistance. The reset impulse is triggered if the line voltage falls below 3V
when the central unit is reset.
The idling current I
R
on the line is calculated as follows:
E

where
R
E
= Original terminating resistor of the line in [Ω]
U
L
= Line voltage in [V]
I
R
= Idle current on the line in [A]
The formulae shown for calculating the terminating resistor and the idling
current on the detection line take account of the ideal status for signal
evaluation.
If no acknowledgement is given from calculating the reset board terminating
resistor, the value of the terminating resistor must be reduced by about 20
%.
The reset board balances the detection line terminating resistor. It is calcu-
lated afresh and incorporated in the reset board (Connection X1, see Figure
“Fitting the rest board into the TITANUS
MICRO·SENS
®
additional housing“).
The value of the terminating resistor R
ER
is calculated as follows:
