Series 9205 Operations Manual Rev A 104
Example: Using quench oil as an example, suppose the SP is 200 °F. The alarm is set as a deviation of +10
°F. At 210 °F, the alarm is active and the pump will run to cool the oil. With a hysteresis of 8 °F, the alarm
and pump will turn off at 202 °F. It will turn back on when it is 10 °F above setpoint. If the setpoint is still
200 °F, then at 210 °F, it will turn on again.
Clicking on this value will display an input box from which the user can select a new value. The range is
from 0 to 9999.
Smart Alarm
This value is a display of the Smart Alarm status. A smart alarm is an alarm that works with a Process
Variable (PV), and, when enabled, it will not be active until the PV is within band of the setpoint. The alarm
sounding - if active - will be disabled until within the SP band. When it is in band, the alarm will go active
unless on delay time is set.
Example: If the SP is 1700 °F and the band is 10 °F, the alarm will not be active until the PV reaches 1690
°F. The value can be either disabled or enabled.
ON Delay Time
This value is the ON Delay Time. Clicking on this value will display an input box from which the user can
select a new value. The range is from 0 to 9999.
0 SP Blocks Alarm
This value will allow a 0 setpoint to block an alarm. The options are either no or yes.
BO/Impedance Inhibits Alarm
This option will allow the user to specify if a burnoff or impedance test will keep the alarm from sounding.
The options are either no or yes.
Inhibit Source
Alarms can be inhibited in order to prevent false or unnecessary alarm notifications. The Inhibit Source
option will allow the user to set the source of the inhibit signal. The options are: None, Input 1 – Input 4,
Soak timer inactive (The alarm will not happen if the furnace is in a soak if this option is selected), and .
Input 6 – Input 15.
Disable on Open Input
An alarm can be disabled when an input the open in order to avoid false or unnecessary alarms. This option
will allow the user to specify if the alarm is disabled when the input is open. The options are either no or
yes.
Thermocouple Check
This menu option allows the values between up to
three thermocouples to be compared to one
another. If the thermocouples go out of band, it is
possible to set up an alarm that will alert the
operators of this error.
Source 1 This assigns the first thermocouple that
will be compared. The options are:
Not used
Instrument 1-27
n/a
Input 3
Input 2 Input 1
