ALP
allocation
From right side to left side, the first, second, third and fourth digit of ALP
individually indicate the alarm output terminal of HIAL, LoAL, HdAL, and LdAL.
0 sh
ows no output. 1 and 2 are spare for future use. 3,4,5 and 6
respectively indicate alarms outputted to AL1, AL2, AU1 or AU2. For
example,
ALP = 5 5 0 3
LoAL HdAL LoAL HIAL
It shows that HIAL is sent to
AL1, LoAL has no output, HdAL and LdAL are sent
to AU1.
Note 1: When AUX is used as auxiliary output in bidirectional
(heating/refrigerating) control, alarm to AU1 and Au2 won’t work.
Note 2: Installing L5 dual relay output module in ALM or AUX can implement
0～5555
CF
System
function
selection
CF is used to select some system function. The value of CF is calculated as
below:
CF=A
1+B
2+C
4+D
8+E
16+F
32+G
64+H
128
A=0, reverse action control mode. When this mode is selected, an increase in
PV results in a decrease in the control output. Ex, heating control.
A=1,
direct action control mode. When this mode is selected, an increase in
PV results in an increase in the control output. Ex, cooling control.
B=0, without the function of alarm
suppressing at power on or setpoint
changing.
C=0,
When the instrument work as a program generator, the upper window
displays the program step; C=1, it displays PV ( measurement value).(only for
AI-518P)
C=0, When the instrument work within HIAL & LoAL,C=1,SV is not litmited(only
for AI-518,not for AI-518P)
D=0, no remote setpoint input function; D=1,allow remote setpoint input. (only
for AI-518P)
D=0, works as transmittion PV value; D=1,give SV output. (only for AI-518)
E=0, disable the function of sectional power restriction
E=1, enable the function of sectional power restriction
F=0, light bar indicates output value.F=1,
light bar indicates measurement
value
G=0,
When alarm is triggered, the alarm symbol is alternatively displayed on
the lower window. It is helpful for user to know the cause of the alarm.G=1,
disable alarm symbol display.
H=0, unilateral hysteresis is applied; H=1,
bilateral hysteresis is applied (in
order to compatible with old version V6.X).
For example: if it is expected that the instr
ument service as reverse action
control; has the function of alarm suppressing at power on; no restriction on
the range of setpoint; no sectional power restriction; no light bar; alternatively
display alarm symbol when alarming, then we get A=0, B=1, C=1, D=0, E=0,
F=0, G=0,H=0. And so parameter “CF” should be set as follows:
CF=0
1 + 1
2 + 0
4 + 0
8 + 0
16 + 0
32 + 0
64 = 2
0～127
Addr
In the same communication line, different instrument should be set to different
address.
0～100
bAud
The range of communication baud rate is 1200～19200bit/s. 0～19200
