3.6 Remote reset terminals
The BA364G Counter may be reset to zero by
connecting the reset terminals RS1 and RS2
together for more than one second.
These two
terminals have the following input and output safety
parameters:
Uo = 3.8V
Io = 1mA
Po = 1mW
Ui = 28V dc
Ii = 200mA dc
Pi = 0.84W
The equivalent capacitance and inductance between
them is:
Ci = 0nF
Li = 0

H
The maximum capacitance and inductance that may
be safely connected between the reset terminals
RS1 and RS2 is:
Co = 40µF
Lo = 1H
The total Counter display may be reset to zero from
within the hazardous area by any mechanically
operated switch contact connected directly to
terminals RS1 and RS2.
To reset the total display
from the safe area a Zener barrier or intrinsically
safe relay is required to transfer the contact closure
into the hazardous area. Almost any intrinsically
safe relay with certification permitting the contacts to
be connected to equipment in the hazardous area
may be used. A positive diode return Zener barrier is
not suitable for this application.
Alternatively, the BA364G Counter may be
configured so that the total display is reset to zero
when the
&
and
*
push buttons are operated
simultaneously for more than three seconds.
See 6.24.
3.7 Certification label information
The certification information label is fitted in a recess
on the top outer surface of the instrument enclosure.
It shows the ATEX and IECEx certification
information, plus BEKA associates name and
location and the instrument model number.
Non
European certification information may also be
included.
