AA
- Analog Output Alarm (Read / Write)
Sets the Analog Output current to a specified value when unit is in any of two alarm conditions. A
Sensor failure (Error Code X107) or Dirty Window Detector circuit failure (Error Code X109) will
trigger this alarm.
Scaled Message Value Range: 0 to 240
Actual Range 0.0 mA to 24.0 mA
AL
– Analog Output Low Temperature (Read / Write)
This command is used to set the value of the current loop output as an alarm if the measured
temperature is below the scaled or default temperature that produces Analog Zero Scale Output
current.
Scaled Message Value Range: 0 to 40
Actual Range is 0.0 mA to 4.0 mA for the 4 to 20 mA current output range.
If the current loop is set for 0 to 20 mA operation, the AL command setting is
overridden and the analog output always goes to 0 mA if below zero scale
temperature.
AH
–
Analog
Output High Temperature (Read / Write)
This command is used to set the value of the current loop output as an alarm if the measured
temperature is above the scaled or default temperature that produces Analog Full Scale Output
current.
Scaled Message Value Range: 200-240
Actual Range: 20.0 mA to 24.0 mA

Head Function Command Codes
CL
– Select Mode of Ratio Sensor Operation (Read / Write)
Command is for 5R ratio units only. The CL command selects One Color or Two Color operation for
a Series 5R ratio Sensor.
Message Value Range: 1 or 2 (1 selects single color brightness mode; 2 selects two color ratio mode).
RT
- Response Time (Read / Write)
Sets the Sensor Response Time.
Scaled Message Value Range: 0 to 6000
(Scaled value = actual value times 100 above Sensor minimum Response Time limit)
Range for Series 52 or 5G Sensors: 0 (Minimum) to 6000 (60 Seconds)
(Zero = somewhat less than .006 second; Zero = not valid for 5R, 56 Sensors)
Range for Series 5R Sensors: 10 (.01 second) minimum to 6000 (60 Seconds)
Range for Series 56 Sensors: 20 (.02 second) minimum to 6000 (60 Seconds)
ES
– E-Slope (Read / Write)
Command is for 5R ratio units only. Sets the E-Slope for Ratio Sensors operating in the 2 color ratio
mode. Function is not active for single color mode.
If the Sensor’s remote scaled E-Slope input current is active, the Sensor returns that setting ignoring
any ES Write command or Rear Panel keyboard entry.
Scaled Message Value Range: 800 to 1200 (Scaled value = actual value times 1000)
Actual Range: .8 to 1.2
