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 minimum 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 minimum 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) If the Bluetooth modem is used, the minimum supply voltage increases by 2 V.
5) 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 minimum error current
(3.6 mA).
