B=1; Change all of the low alarm to be low deviation alarm; when deviation
value (PV – SV) < L.ALx, it will trigger the alarm. When (PV – SV) > L.ALx –
HYSx, alarm off, set the L.ALx value to minimum will disable the alarm
function.
nonc
NO/NC
selection
Single channel relay module provides both normal open and normal close
output, while dual relay output module L5 only provides normal open output.
However, by parameter “nonc”, the NO output can be changed to NC output.
nonc = 0, AL1, AL2 (L5 is installed in ALM socket) are normal open output.
nonc = 127, AL1 and AL2 are normal close output
0, 127
Loc
Parameter lock
Loc=0, Allow to display and modify parameter “Loc” and the field parameters
which is defined in EP1~EP12 .
Loc=1, Allow to display and modify parameter “Loc”, and only display field
parameters, can’t modify them.
Loc=808, allow to display and set all parameters.
Note: This setting just effect on external display. Modify parameter by
communication was always allowed.

Field
parameter
When configuration of the instrument is completed, most parameters will not
need to be set by field operators. Furthermore, field operators may not
understand many parameters, and may probably set parameters incorrectly
by mistake and make the instrument unable to work.
EP1~EP12 define 0~12 field parameters for operators’ use in parameter
table. Their parameter values are parameters except parameter EP itself, for
example, H.AL1, L.AL1, .etc,
Parameters from EP1 to EP12 can define 12 field parameters at most, if the
number of field parameters is less than 12(sometimes even none), it is
necessary to define field parameters from EP1 to EP12 in order, the first
unused EP should be set to none.
For example, four parameters of SP1 to SP4 (all channels’ setpoints) are
need to be modified by field operators, the parameter EP can be set as :
EP1=SP1, EP2=SP2, EP3=SP3, EP4=SP4, EP5=none, Loc=0
Then only parameter SP1~4 can be displayed and modified, but via
communication, on the host computer, all parameters can be displayed and
modified.
