a. The maximum value of the Hydran 201Ci-1's display scale is 1999 ppm. If the signal is over
scale, the display indicates 1... when the operation mode is set to Force 100 %.

TDM Out

• TDM State: Displays the state of the Hydran 201Ti's TDM signal, in percentage.
– Used with the H201Ci-1 Controllers only, the TDM signal is integrated to the
supervisory link and is used to transmit the state of the H201Ti's alarm relays and
analog output. Only one pair of wires is necessary to transmit this information. For
details on the supervisory link, see Section 9.1 on page 9-1.
– The TDM signal relates to the gas level being measured. The displayed percentage is
thus directly proportional to the gas level (% output = ppm/20; 2,000 ppm = 100 %).
• TDM Mode: Is used to set the operation mode of the TDM signal. The three Force x %
modes are used only to test the operation of the Hydran 201i System.

NewSensor Submenu (Extended Menu Only)

The NewSensor submenu is used to:
• Set the Hydran 201 sensor parameters.
• Install a new H201 sensor.
This submenu is very similar to the Service;SensorCal Data submenu (see Section 4.5.4.1
on page 4-18), except that in the latter submenu the parameter values cannot be changed.
The NewSensor command requires password No. 2. The H201 sensor is then immediately
tested and the result (Good or else) is displayed after three seconds. For details, see
Section 4.5.4.2 on page 4-19.
