Note: For example, the reading range of a Magnetic-Mount Temperature
Transmitter (part number 13298) is -40 to 150 ºC. For this sensor, the Input
Min. parameter would be set to -40 ºC and Input Max. to 150 ºC.
– Input Resolution: Degree to which the result of the reading approximates
the true reading. Set this parameter only if discrete values need to be
displayed (for example, in the case of a tap changer position); otherwise, it
is set to 0.
– Alarm Setup: These parameters are identical to the ones in Alarms > Alarms
Setup > Analog Input Alarm Setup. See Section 3.3.2.5.
3.2.9.2 Analogue Output Setup
The An. Output Setup function is used to set up the optional analog output
signal.
• Analog State: Displays the state of the Hydran M2-X’s analog output as a
percentage of the maximum electric current. The analog output provides the
gas level being measured; the displayed percentage is thus directly proportional
to the gas level. For details on the analog output, see Section 2.3.2 and Section
K-1.
• Analog Mode: To set the operation mode of the analog output. The three
Force x % modes are used only to test the operation of the Hydran M2-X.
Table 3-4 shows the electrical current generated for each mode.
Type of Output
Operation Mode
Force 0 %
Force 50 %
Force 100 %
4–20 mA
4.00 ± 0.10 mA
12.00 ± 0.20 mA
20.00 ± 0.40 mA

3.2.9.3 TDM Output Setup
The TDM Output Setup function is used to set up the TDM output signal. The TDM
signal is monitored by a Hydran 201Ci-1 or Hydran 201Ci-4 Controller.
• IO State: Displays the state of the TDM signal in percentage. The displayed
percentage by IO State is thus directly proportional to the gas level (% output =
ppm/20; 2,000 ppm = 100 %).
• IO Mode: Used to set the operation mode of the TDM signal. The three Force x %
modes are used only to test the operation of the TDM signal.
• Comm #2 TDM Relay A: Used to select a first relay. The state of this relay will be
transmitted in the TDM signal.
• Comm #2 TDM Relay B: Used to select a second relay. The state of this relay will
be transmitted in the TDM signal.
• Sample Rate: To set the frequency at which the signal is updated.
