Chromalox 1604 User Manual

16
2 = Safety value applied when overrange
condition is detected.
3 = Safety value applied when underrange
condition is detected.
P38 = Output safety value
This parameter is skipped when P37 = 0
This value can be set
- from 0 to 100 % when P7 is different from 4
- from -100 % to 100 % when P7 is equal to 4
P39 =Extension of the anti-reset wind up
Range: from -30 to +30 % of the proportional
band.
NOTE: a positive value increases the high limit of
the anti-reset-wind up (over set point) while a
negative value decreases the low limit of the anti-
reset-wind up (under set point).
P40 = Control action type
Pid - the instrument operates with a PID algorithm.
Pi - the instrument operates with a PI algorithm.
P41 = Set point indication
Fn.SP = during operative mode, when the
instrument performs a ramp, it will show
the final set point value.
OP.SP =during operative mode, when the
instrument performs a ramp, it will show
the operative set point.
P32 = Minimum value of the integral time
calculated by the SMART algorithm.
This parameter is present only if P27 is different
from 0.
It is programmable from 1 second (00.01) to
2 minutes (02.00).
P33 = Device status at instrument start up.
This parameter is skipped when P26 = OFF.
0 = the instrument starts in AUTO mode.
1 = It starts in the same way it was left prior to
power shut down.
P34 = NOT AVAILABLE
P35 = Timeout selection
This parameter allows to set the time duration of
the timeout for parameter setting used by the
instrument during the operating mode.
tn. 10 = 10 seconds
tn 30 = 30 seconds
P36 = Digital filter on the measured value
It is possible to apply to the displayed value a
digital filter of the first order with a time constant
equal to :
- 4 s for TC and RTD inputs
- 2 s for linear inputs
noFL. = no filter
FLtr = filter enabled
P37 = Conditions for output safety value
0 = No safety value (see"Error Messages" Chapter)
1 = Safety value applied when overrange or
underrange condition is detected.
