The Searchzone Sonik features HART communications to provide access to the detector from a control system or hand-held device for
the purpose of configuration and to provide status and diagnostic information.
The total load resistance for the 4-20 mA current loop shall be less than 600 Ω, including the resistance of the 4-20 mA cable and
input impedance of the equipment to be connected. To ensure reliable HART communications, the minimum loop resistance is 250 Ω.
If HART communications is not required, the minimum loop resistance is 100 Ω.
If the 4-20 mA current loop is not used, a jumper must be connected between 4-20 mA+ (terminal 5) and 24V DC+ (terminal 8) and a
load resistor must be connected between 4-20 mA- (terminal 6) and 0V DC (terminal 9). It is recommended to use a 470 Ohm, 1/4 W
resistor (250 to 400 Ω if HART is required). With the 4-20mA current loop configured this way the HART facility can still be used with a
HART hand held unit using terminals 20 and 21 inside the wiring compartment.

CAUTION
The maximum permissible mA loop voltage is 32 VDC and the maximum current is 22 mA.
