Configuration; Threshold Setting; Zero Point Calibration - Honeywell H-S81-HS Operation Manual

Parts of the H-S81-HS System
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.

Configuration

By using the configuration program ProS81, the following parameters can be set for each input
channel:
Function
Operating mode
Mode of analog value transfer to Hosts
Unit of measure of the channel
Zero Point of the measuring range
End of scale of the measuring range
Pre-alarm threshold
Alarm threshold
Lower trouble threshold
Alarm delay
Type of indication
Automatic alarm reset
Enable/Disable status export via ModBus
Enable/Disable channel status export to Hosts
Enable/Disable commands from Hosts on the channel
It defines the format of the analog value sent via ModBus,
and automatically via Host

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 zero point can be calibrated only with zero values ranging between 3 and 5mA.
