OP1 output type
OP1 select the control output type:
OP1=OP1.A x 1 + OP1.B x 10
OP1.A shows the output type of OUTP. It should be compatible w
ith the
module installed in OUTP sockets.
OP1.A=0,
if output modules such as SSR voltage output, relay contact
discrete output, thyristor cross zero trigger output, and TRIAC no-contact
discrete output are installed in OUTP.
OP1.A=1, 0～10mA linear curren
t output. Linear current output module
should be installed to main output.
OP1.A=2, 0～
20mA linear current output. Linear current output module
should be installed to main output.
OP1.A=3, spare
OP1.A=4, 4~20mA linear current output. Linear current output module
should be installed to main output.
OP1.A=5～7, is for other models, please not use it for AI-518/518P.
OP1.A=8, single channel phase-
shift output. K5 module should be
installed. AUX can not work as refrigerating output.
OP1.B shows the AUX output type. It works only when parameter oPL<0.
OP1.B=0, time proportional output.
Output modules such as SSR
voltage output, relay contact discrete output, thyristor cross zero trigger output,
and TRIAC no-contact discrete output can be installed in OUTP.
OP1.B=1, 0～
10mA linear current output. Linear current output module
should be installed to main output.
OP1.B=2, 0～
20mA linear current output. Linear current output module
should be installed to main output.
OP1.B=3, spare
OP1.B=4, 4～20mA linear current output.
Linear current output module
should be installed to main output.
AUX does not support position proportional output or phase-
shift trigger
output.
For example, OUT and AUX all output 4～
20mA linear current, then
OP=44.

OPL Output low limit
0
～
110%: OPL is the minimum output of OUTP in single directional control
system.
-110 ～ -
1%: the instrument works for a bidirectional system, and has
heating/refrigerating dual output. When CF.A=0, OUTP (main output) works
for heating, and AUX (Auxiliary output) works for refrigerating. When CF.A=1,
OUTP works for refrigerating, and AUX works for heating.
In a bidirectional system, the heating and refrigerating ability are generally
different.
OPL = -
(power when AUX output is maximum /power when OUTP output is
maximum) x 100%.
For example, for a heating/refrigerating air condition, its maximum power of
refrigerating is 4000W, and maximum power of heating is 5000W, and AUX
works for refrigerating, then
OPL=- (4000/5000)x100% = -80%
The range of AUX output can’t be fre
ely defined by user. If the internal
calculation requires maximum output of AUX (AUX output=OPL), then in 4～
20mA output, the AUX output is 20mA, and user can’t limit the maximum AUX
output to 10mA.

Output upper
limit
OPL limits the maximum of OUTP (main output). OPH should be greater than
OPL.
