See Figure 2-11.
Note: The zero function may be activated as part of a periodical
maintenance check. If desired, a zero switch can be remotely mounted

The alarm contact and pulse output digital signals are electrically
identical, independent, optically coupled transistor outputs. Wiring will be
as required by the external driven system - Prover, DCS/PLC, terminal-
automation system, batch controller etc. These can be wired as an open
collector or open signal on the high or low side of voltage-rail within the
receiving equipment, depending upon the signal needs. When interfacing
to external electronics, be careful to work within the voltage/current

i. Intrinsically safe installations require the use of barriers, power supply
limits and cable parameters. All connections are made in the transmitter
housing.
Refer to Table 1-12 in approvals section and Figures 2-5a/2-5b and
