(contd.)
4. In the case of damage:
a) Leave item(s) in the original packaging
b) Do not attempt repair, or operate the detector until the damage claim has been resolved with
the supplier.
5. Installation, set-up and maintenance must be conducted only by trained and authorized personnel.
6. Do NOT open the front enclosure. The warranty of a unit, whose front enclosure has been opened, is
invalidated. Front enclosures may be opened only for advised repair maintenance by an authorized
and qualified person.
7. Do NOT modify the front enclosure or component parts as this will compromise the hazardous location
certification and invalidate the warranty. Front enclosures may be opened only for advised repair
maintenance by an authorized and qualified person.
8, Do NOT modify the construction of the detector in any way as this will invalidate the warranty.
9. Open and close the wiring compartment cover with care to avoid deformation.
10. Installation, set-up and maintenance must be conducted only by trained and authorized personnel.
11. Avoid water and dust ingress when opening the wiring compartment to protect the unshielded
electronic contacts.
12. Secure the detector when loosening bracket bolts. Unwanted release may cause injury.
13. Check mating surfaces prior to assembly (threads, O-rings). Ensure that they are clean and free of
contaminants.
14. Check the O-rings prior to assembly, replace if damaged with genuine parts.
15. Searchline Excel Plus is supplied without cable glands. Ensure that all cable entry threads are sealed
with an appropriate plug to eliminate water ingress and thread damage. At installation, the cable entry
transportation plugs must be removed and replaced with suitable cable glands, thread adapters or
blanking plugs to meet local hazardous location requirements.
16. Check suitability of the blanking plug for its end use on site, ensure it meets local and national
regulations.
17. Remove power from the Searchline Excel Plus instruments while installing wiring. Do NOT install wires
or set up wiring with power applied.
CAUTION
!
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.
Searchline Excel Plus will normally be mounted at height, typically on a pole using supplied U–bolts and
covering the area to be protected. The supplied Universal Mounting Bracket allows mounting on a plate,
pole or other plant infrastructure. All bolts are retained to avoid loss during installation.
Searchline Excel Plus has two cable entries for easy wiring with either M25 or 3/4" NPT options. Wires are
terminated at the terminal connectors as per the wiring diagram. Spare wires must be suitably terminated.
Wiring must be in accordance with local, national and company regulations. Exposed or bare wires must
be avoided.
