Searchline Excel™ Plus / Searchline Excel™ Edge – Technical Manual
6.1.1.1Receiver Internal Battery Cell
A primary cell featuring an expected operating life of 10 years is fitted internally. This is not accessible and replacement
must only be conducted by an authorized service centre.
6.1.2Receiver 420 mA Current Loop
The receiver provides a 420 mA current loop with HART Communication which can be user configured as a Sink, Source
(3Wire) or Isolated (4Wire) electrical interface, based on installation requirements.
Depending on configuration, the 420 mA current loop output can provide:
• discrete indication of operating modes (Normal operation, Pre-alarm, Alarm) and special states (Fault, Warning, Inhibit,
Over-range)
• proportional output to gas concentration and a discrete indication of special states (Fault, Warning, Inhibit,
Over-range).
Searchline Excel Plus & Searchline Excel Edge features HART communications to provide access to the receiver from
a control system or handheld 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 communication 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20 mA current loop
configured this way the HART facility can still be used with a HART handheld unit using terminals 20 and 21 inside
the wiring compartment. A HART DTM is available for Searchline Excel Plus and Searchline Excel Edge.
CAUTION
!
The maximum permissible mA loop voltage is 32 VDC and the maximum current is 22 mA.
6.1.3Relays
The receiver features 3 SPDT relay outputs for alarm and fault indication. Relay 1 is for alarm level 1, relay 2 is for alarm
level 2, and relay 3 indicates faults. The fault relay is normally energized and when energized indicates proper operation
(no faults present).
In the event of power failure or fault, the COMNO connection will open. If required, the fault relay may be configured as
normally de-energized.
