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). 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).
