P21 = Alarm 3 delay and overrange mask
This parameter is available when P11 different
from none.
enb = the two special functions are enabled
DIs = the two special functions are disabled.
For other details see P19 parameter.
P22 = Servomotor control action
Available when P5 = SM.CL or SM.OL.
REU = reverse control action
DIR = direct control action.
P23 = Feedback potentiometer selection
Available only when P5 is equal to "sm.Ol" or
"sm.CL".
0 = from 300 to 1000 Ω potentiometer
1 = from 100 to 300 Ω potentiometer
P24 = Logic input 2 function (contact)
none = Logic input 2 not used
aU.mA = Logic input 2 used for AUTO/ MAN
control mode selection.
Open = AUTO
Closed = MANUAL
NOTE: the "serial comunication" and the "logic
input" options are mutually exclusive.
P25 = Cooling media.
Available only when the device is configured with
two control outputs.
air = Air OIL = Oil H2O = water
Changing P25 parameter, the instrument forces
the cycle time and relative cooling gain parameter
to the default value related with the chosen cooling
media.
When P25 = AIr - CYx = 10 s and rC = 1.00
P25 = OIL - CYx = 4 s and rC = 0.80
P25 = H2O - CYx = 2 and rC = 0.40
From 2 to 4999 = This combination number is a
secret value to be used, in run time (see nnn
parameter) to put device in lock/unlock
condition.
With this selection, the lock/unlock condition
has no effect on SP, SP2 and manual reset of
the alarms (for SMART status see P33).
From 5000 to 9999 = This combination number is
a secret value to be used, in run time (see
nnn parameter) to put device in lock/unlock
condition.
With this selection, the lock/unlock condition
has no effect on SP, SP2, manual reset of the
alarms and AL1/ AL2/ AL3 thresholds (for
SMART status see P33).
P19 = Alarm 1 delay and overrange mask
Two special function are driven by this parameter:
1) When the instrument detects an alarm condition
it waits for 6.5 s before tho activate the alarm. If
the alarm condition disappares during this time,
the alarm will not be activated otherwise it will
operate as usual.
2) When the instrument detects a very high overrange
(like for OPEN TC), it will mask this alarm.
This parameter is available when P7 is different
from none, rEU or dir.
enab = the two special functions are enabled
DIsa = the two special functions are disabled.
P20 = Alarm 2 delay and overrange mask
This parameter is available when P9 is different
from none.
enb = the two special functions are enabled
DIs = the two special functions are disabled.
For other details see P19 parameter.
