Table 3.2 Configurable Parameters
Display Function
(In order of Display)
SP1
Set Point 1
Range
Function
-19999 to +19999
Sets first output trip or control
(Chapter 5 refers)
SP2
Set Point 2
-19999 to +19999
Sets second output trip or control (Chapter 5
refers)
HYS
Hysteresis
0 to +19999 in real display units
Sets hysteresis applied to SP1 and SP2 when used
for ON/OFF control units (Chapter 5 refers)
OL
Output Latch
Latch set by code in range0-3 as
shown in Table 5.1
Allows SP1 and/or SP2 to be latched
until reset externally, from the keypad or via
communications port.
OA
Output
Action
(Inversion)
of SP1 & SP2
Action set by code in range0-15
as shown in Table 5.2
Pb
Proportional
Band
0 to 1024
Sets output relay action. Can be set
to ‘normal’ or ‘inverted’ operation for either or
both set points. Gives fail safe operation of any
alarm combination, High-High, High-Low, LowHigh & Low-Low. (Chapter 5 refers) Also selects
whether analogue outputs controlled by display
module or PID element in CPU Inversion of the
analogue output
'O' Selects 'Ont'.'Offt' or 'da' function 1-1023
Selects PID mode and value of proportional band,
in displayed units. 1024 Selects Integral 'It' only
control
Ont
Output on
delay
0 to 255
When PID is not used, (PB=0) the mnemonic (Ont)
sets a delay on time for SP1 & SP2. Set in
seconds.
Or
(It)
Integral
0 to 6000
Selects integral value for PID control in
seconds/repeat. 0= Proportional only control.
OFFt
Output off
delay
0 to 255
When PID is not used,(PB=0) the mnemonic (Offt)
sets a delay off time for SP1 & SP2 set in
seconds.
Or
(dt)
Derivative
Time
0 to 255
Selects derivative value for PID control. 0 = OFF
(no derivative)
dA
Display
Averaging &
Peak Hold
0 to 15
When PID is not used,(PB=0) the mnemonic (dA)
sets a display averaging update rate.
Readings may be averaged over a number of
updates and can be set as follows:
