By setting the register to 1 the MIN, MAX, RESET, RAMP values will only be read by the following
registers:
40004
40004
MAX - Max. PWM value
(0-8191) value that can be
set
Writing max. PWM value
40005
40005
MIN - Min. PWM value (0-
8191) value that can be
set
Writing min. PWM value
40006
40006
RESET - PWM Reset
value (0-8191) value that
can be set
PWM reset value writing
40007
40007
RAMP - PWM Ramp
value (0-8191) value that
can be set
PWM ramp value writing
The trimmers are no longer used.
-
By setting the register to 2, the MIN, MAX, RESET, RAMP values are read by the above registers
and the trimmers can be used for fine /- 12.5% in relation to the value set in the register.
Switching switch 1 of the
SWC
bank
ON
activates the voltage insulator function. In other words an analog
input is read and its value is transferred proportionally to the Current Loop output. The LEDs on the front
panel remain lit in this mode.
In this mode,
SWE
dip switches 5 to 8 are no longer read and a CanBus interface will be disabled.
Using digital input
UP (PIN 5 of J5)
you can select which digital input will be used for the handshaking:
-
With input UP inactive (open), the 0-5V digital input is acquired
-
With input UP active (closed), the 0-10V digital input is acquired
In voltage isolator mode the DIPOT lets you decouple, transfer, and reduce or increase the acquired
voltage value.
The current range (± 20mA, ± 10mA, 0-20mA), between the two output terminals (+ C.L. and -C.L.), can
be selected with a switch on the Current Loop output, simply connect a suitable resistance to obtain the
desired voltage range (
±11V
).
With suitable settings in the following registers we can limit the acquired voltage value making it also
asymmetrical in relation to the output, if desired:
40015
40015
Min. 0-5V input percentage
limit for Voltage isolator
40016
40016
Max. 0-5V input percentage
limit for Voltage isolator
40017
40017
Min. 0-10V input percentage
limit for Voltage isolator
40018
40018
Max. 0-10V input
percentage limit for Voltage
