Set Point Limit (L) - Process Technology DQ15D Instruction Manual

Temperature Sensor - Number represents degrees Celsius or
Fahrenheit as determined by the "F5" setting
Voltage Sensor - Number represents tenths of a volt (0.1 VDC)
Current Sensor - Number represents hundredths of milliamps
(0.01 mA)
Resistance Signal Devices - Number represents ohms
Frequency Signal Devices - Setting represents hertz (counts/second)
This bandwidth applies to the low side of the "SP2" SET POINT. If the
"U5" setting is set at 5º F and the "SP2" SET POINT is set at 115º F, then
the set point relay is de-energized when the (displayed) temperature reaches
115º F and will remain energized until the temperature falls to 110º F.
Note: The default and minimum for the setting is one (1).
U7, Power-Save Set Point Dead Band
This setting, which may be any number from 1 to +99, represents a dead
band that only applies to the POWER SAVE SET POINT.
Temperature Sensor - Number represents degrees Celsius or
Fahrenheit as determined by the "F5" setting
Voltage Sensor - Number represents tenths of a volt (0.1 VDC)
Current Sensor - Number represents hundredths of milliamps
(0.01 mA)
Resistance Signal Devices - Number represents ohms
Frequency Signal Devices - Setting represents hertz (counts/second)
If the POWER SAVE SET POINT dead band setting is set at 10º F and
the POWER SAVE SET POINT is 75º F, the "SP1" relay de-energizes
when the display temperature reaches 75º F and is reenergized when the
temperature falls to 65º F.
U8, Display Stabilizer
If the display value changes by a digit or two in a steady state condition,
this setting can be altered in conjunction with the "U4" setting to reduce
the display instability. Lower values cause maximum suppression. Larger
values provide greater accuracy.

The default value for the U8, Display Stabilizer setting is ten (10).
L, Set Point Limit
This setting, which may be any number between -99 and +999, is the
maximum limit for all SET POINTS except the ALARM SET POINT.
This will prevent accidental setting of a set point, which could be too high
or low (depending upon the application).
Temperature Sensor - Number represents degrees Celsius or
Fahrenheit as determined by the "F5" setting
Voltage Sensor - Number represents tenths of a volt (0.1 VDC)
Current Sensor - Number represents hundredths of milliamps
(0.01 mA)
Resistance Signal Devices - Number represents ohms
Frequency Signal Devices - Setting represents hertz (counts/second)
Note: The default value for this setting is +999.
F1, "SP2" and "U7" Disable
This setting may be either a one (1) or a zero (0), and controls the behav-
ior of the DQ15D by making it perform like the single set point PRO-
CESS TECHNOLOGY model DE control. When this setting is set to
one (1), it is "ON". The "SP2" Set Point and the "U7" Power Save Set
Point are both disabled and will not work.
F2, Heating or Cooling Switch
This setting is not applicable for the DQ15D control.
F3, Alarm On/Off Switch
This setting may be a zero (0) or a one (1). When set to zero, the alarm
set point is turned off. When set to one, alarm set point is turned on.
Note: The default value for this setting is zero (0).
