Wiring graph of instruments with D2 dimension as below:
Note 1
: D4 dimension instruments don’t
support 0
～
5V or 1
～
5V linear voltage input.
However, 0
～
5V or 1
～
5V signal can be
converted to 0
～
500mV or 100
～
500mV by
connecting external precise resistors, 4
～
20mA can be converted to 100
～
500mV by
connecting a 25ohm resistor, then be inputted
from terminals 9 and 8.
Note 2
: For COMM/AUX slot, if S or S4
communication module is installed, it can be
used for communication; if L2 module is
installed in, parameter set bAud = 0, it can be
used for AU1 or AU2 alarm output; if set
parameter bAud = 2, it can be used for AU1 or AL1 alarm output. If L1, L2, L4, G, K1, W1 or W2 is installed, it can be
the auxiliary output in bidirectional (heating/refrigerating) control (Auxiliary output doesn’t support analog current
output); if I2 is installed and bAud = 1, then it can input on-off signal to switch SP1 and SP2 (AI-526) or switching the
program status RUN / Stop (AI-526P) by connecting a switch between terminals number 3 and 5.
