Searchline Excel™ Plus / Searchline Excel™ Edge – Technical Manual
10.3.1First Time Switch On
Note:
Searchline Excel Plus & Searchline Excel Edge are supplied ready for use. They do not require calibration during
commissioning. Zeroing may be required during functional testing.
Note:
During commissioning the 420 mA output can be monitored either at the control room or locally with a multimeter.
When connecting or disconnecting a multimeter, power off Searchline Excel Plus & Searchline Excel Edge, otherwise
the detector will indicate a latched warning that the 4–20 mA loop was broken. If this occurs it can be cleared using
HART communications.
1. Before applying power to the detector, ensure that the field wiring is correct and all electrical connections are correctly
set up. Refer to the Electrical Installation chapter of this manual for more information.
2. Apply power. Check that the supply voltage to Searchline Excel Plus & Searchline Excel Edge is between 18 and 32 Vdc.
Monitor the 420 mA output during the start-up sequence, which should be as follows:
CURRENT OUTPUT DURATION
< 1 mA < 30 s
4 ± 0.05 mA ongoing
Note:
Depending on the mA Operation Mode that is selected, if gas leak is present, the detector will indicate a gas leak SPL reading.
Note:
If the output reverts to 3 mA or < 1 mA, a Warning or Fault is present. Follow the instructions below to investigate and clear
a Warning or Fault (see Clear Faults or Warnings).
If local regulations or site practices require that a gas leak test is done to check that the detector is functioning, refer to
Chapter Maintenance for more instructions.
10.3.2User Configuration
10.3.2.1Parameter Checker
The Parameter Checker verifies conditions across all variables each time a change in configuration is requested.
If one of the checks fails an error is reported containing:
- Error code
- Parameter ID 1 (if appropriate)
- Parameter ID 2 (if appropriate)
10.3.2.2Change the Password
CAUTION
!
For product and data security, it is important that the password for ‘Engineer’ profile access is changed from
the default setting.
The password is 8 digit alphanumeric (case sensitive). A full 8 digit password should be used.
1. Select Device Setup.
2. Select Account.
3. Select Change Password.
4. Enter the password xxxxxxxx (eight characters, Alphanumeric, case sensitive) and press Enter.
5. The display shows a confirmation message, press OK.
6. Press Back to return to the Device Setup menu.
Note:
Some HART handheld devices contain a default password or hold a previously used password. Ensure that the desired
password is entered in before pressing Enter.
10.3.2.3Set the Time and Date
Searchline Excel Plus & Searchline Excel Edge have a real time clock, which is factory set to UTC time.
CAUTION
!
Do NOT set HART to nonUTC time. The Fixed Platform App auto-translates detector’s UTC timestamps
to local timestamps. Changing detector’s UTC setting may cause connection issues.
