Parts of the H-S81-HS System I/O modules
Configuration
By using the configuration program ProS81, the following parameters can be set for each input
channel:
Threshold Setting
The following parameters can be set for each module through the configuration program or directly
on the control panel in the operator cycle, access level 3:
• Pre-alarm threshold.
• Alarm threshold.
• Current value below which a trouble condition is signaled.
• Calibration mixture concentration value for end of scale calibration.
Zero Point Calibration
Calibrate the zero point as reported below:
• Disable the channel of the module to be calibrated from the operator cycle.
• Enter the diagnosis cycle of the module to be calibrated.
• Make sure that no gas is present near the sensor to be calibrated.
• Press the “1” key to calibrate the zero point of the channel 1.
• Press “0” to cancel the operation for the channel 1.
• Press the “5” key to calibrate the zero point of the channel 2.
• Press the “4” key to cancel the operation for the channel 2.
• Exit the module diagnosis cycle and enable the channel.
NOTE: The two 3-digit displays on module front panel do not provide the operator with
fundamental information and do not comply with the standard EN-54-2.
