OPL
Low limit of
retransmission
current
When OUTP works as re-transmitter, OPL/OPH define the
low/high limit of re-transmisson. The unit is 0.1mA.
For example, to transmit the channel 1 input 0~600
★
into
4~20mA output, the parameters should be set as below:
dIL1=0, dIH1=600, OPn=1, OPL=40, OPH=200
0~110
OPH
High limit of
retransmission
current
0~220
Po
Atmospheric
pressure
Defined atmospheric pressure, when dry bulb, wet bulb
humidity measurement activated. Unit = KPa
1~120.0
SPEd
Wind speed
Defined wind speed, when dry bulb, wet bulb humidity
measurement was activated. Unit = m/S
0.01~10.00
Addr
Communication
address
Every instrument in the same communication line should
be assigned to different communication address. The
communication applies AIBUS protocol. Every input
channel takes one address. For example, if Cn=3 and
Addr=10, then the communication address 10~12 are
assigned to the instrument.
0 ~100
bAud
Baud rate
When COMM module interface is used for communication,
bAud defines the baud rate with range 300~19200bit/s.
When linear current output module is installed in COMM
socket, and bAud is set to 0~220, the COMM output can
work as retransmission output. It can retransmit channel
2 input or cyclically retransmit all input channels into linear
current. bAud defines the output high limit, and Addr
defines the low limit. The unit is 0.1mA. For example,
to output 4~20mA current, Addr should be set to 40, and
bAud=200.
0 ~19.2K
Loc
Parameter lock
Loc=0: Allow to display and modify the field parameters
only, which is defined in EP1~EP12.
Loc=1: Display the field parameters, without modification.
Loc=808: Allow to display and set all parameters.
0 ~9999
EP1-12
Field
parameter
When configuration of the instrument is completed, most
parameters are able to hide from field operators to avoid
improper configuration.
EP1~EP12 define none or up to 12 field parameters for
operators from parameter table, except EP itself, like
H.AL1, L.AL1 and.etc.
If the number of field parameters required is less than
12(sometimes even none), define field parameters from
small number, the next unused EP set to NonE.
E.g. Six parameters of H.AL1 to H.AL6 (all channels’ upper
alarm) are need to be modified by field operators, EP
setting are as follows:
EP1=H.AL1,
EP2=H.AL2,
EP3=H.AL3,
EP4=H.AL4,
EP5=H.AL5, EP6=H.AL6, EP7=NonE.
If no field parameter is required, just set EP1=NonE, then
set Loc to 0 or 1.
