SECOND SETPOINT (SP2)
SECOND SETPOINT (SP2) Alarm Output
Configure SP2 output to operate as an alarm from
SP2.A
in Level 2 and set the temperature alarm setting in
SEt.2
Level 1. The
alarm will be triggered when the process temperature changes according to the options listed below.
dV.hi
Rises above the main setpoint by the value inserted at
SEt.2
.
dV.Lo
Falls below the main setpoint by the value inserted at
SEt.2
.
Band
Rises above or falls below the main setpoint by the value inserted at
SEt.2
.
FS.hi
Rises above the main setpoint by a
SEt.2
value that is greater than the setpoint.
FS.Lo
Falls below the main setpoint by a
SEt.2
value that is smaller than the setpoint.
SUBSIDIARY SP2 MODE
The following additional alarm functions can be added to the above alarm configurations using the features found in
SP2.b
in Level 2
LtCh
Once activated, the alarms will latch and can be manually reset when the alarm condition has been removed.
Hold
This prevents any alarm operation on power-up and is automatically disabled once the process reaches setpoint in
order to allow normal alarm operation.
Lt.ho
Combines the effects of both
LtCh
&
Hold
and can be applied
SECOND SETPOINT (SP2) Proportional control output
Configure in
Level 1
using
CyC.2
to select proportional cycle time and
bnd.2
to adjust proportioning band.
- For Heat/Cool operation see full operating manual.
- In on/off mode, bnd.2 adjusts SP2 hysterisis.
SP2 OUTPUT AND LED INDICATION STATES - IN ALARM CONDITION
SP2 ALARM ANNUNCIATOR
When an SP2 alarm mode is selected in SP2.A the alarm annunciator
-AL-
is displayed, alternating with the process temperature,
during alarm condition.
Notes:
The alarm will be automatically reset when the temperature returns within the
bnd.2
setting in Level 1.
The annunciator may be disabled by selecting function
no.AL : on
in level 4.
