Endress+Hauser PROMAG 33 - Functions of the Auxiliary Input

Functions of the auxiliary input
With “PULSED MODE”
Assignment Pulse at auxiliary input Function Remarks
RESET TOTALIZER • No pulse
• Pulse between 3...30 V DC;
at least for the duration of the
set start pulse width.
No function
Totalizer (incl. overflows)
is reset
–
BATCHING • No pulse
• Pulse between 3...30 V DC;
at least for the duration of the
set start pulse width.
• Another pulse during the filling
procedure (at least for the
duration of the set start pulse
width).
No function
Batching cycle is started.
Batching cycle is stopped.
The “BATCHING” option is only
available, if the function “BATCH
VARIABLE” is set to “VOLUME”
(see page 64).
By deactivating the batching
function, the auxiliary input is
automatically set to “POS. ZERO
RETURN”.
With “LEVEL MODE”
Assignment Voltage at auxiliary input Function Remarks
DUAL RANGE MODE • No voltage
• Voltage of 3...30 V DC
Current output operates with
FULL SCALE 1
Current output operates with
FULL SCALE 2
The “DUAL RANGE MODE”
option is only available, if the
current output is switched on
and the dual range mode is
activated.
If the current output is switched
off or the dual range mode
deactivated, then the auxiliary
input is automatically set to
“POS. ZERO RETURN”.
POS. ZERO RETURN • No voltage
• Voltage of 3...30 V DC
Instrument operates normally.
All output signals are set to “0”
(corresponds to no flow).
No simulation of current or
frequency signals is possible
when “Positive zero return” is
activated.
