FlowShark Pulse Power Supply
FlowShark Pulse models are equipped to operate using either 85-260V AC
(alternating current) or 24 V DC (direct current) power. Two on/off slide switches
exist above the terminals. The 24V switch (Figure 6-35) powers up or down the
auxillary 24-volt DC output and powers down 24-volt DC input.
Figure 6-35 Slide switch position on the bus board
A 24 V DC transmitter cannot be operated with alternating
current; a 230 V AC transmitter cannot be operated with direct
current.
Before connecting a power source to the unit, move the 230V and 24V switches to
the off position. For AC power, wire the 120 V circuit to L1, N, and PE (Figure 6-
36). For 24V DC power, wire to terminals b2 (+) and b3 (–), as shown in Figure 6-
37. If the unit is AC-powered, 24V DC auxillary power is available, as shown in
Figure 6-36 (24V DC, 100 mA maximum).
