3) For ambient temperatures T
a
≤ -30 °C (-22 °F) a minimum voltage of 14 V is required for the sartup of the device
at the MIN error current (3,6 mA). For ambient temperatures T
a
≥ 60 °C (140 °F) a minimum voltage of 12V is
required for the sartup of the device at the MIN error current (3,6 mA). The startup current can be parametrized.
If the device is operated with a fixed current I ≥ 4,5 mA (HART multidrop mode), a voltage of U ≥ 11,5 V is
sufficient throughout the entire range of ambient temperatures.
4) For ambient temperatures T
a
≤ -20 °C (-4 °F) a minimum voltage of 16 V is required for the startup of the device
at the MIN error current (3.6 mA).
