UNIT WILL NOT DELIVER 24Vdc LOOP SUPPLY OUTPUT
If the HHC is an Intrinsically Safe base unit , then loop supply is
not available.
Reference the manual section 14k to enable and disable the
power supply. Attempt to enable the supply. Ensure that the
“24V” icon appears on the display of the HHC.
If the power supply has been overloaded and a warning message
shows on the display (supply current is specified at 35ma and will
overload at approximately 54-55ma)
Remove the overload from test circuit and enable the 24 VDC
power supply via MENU commands. (See section 14k)
Ensure that the supply is being measured between the”24Vdc
Out” jack and the “COM” output jack at the top of the HHC.
Check all connections and wires in the set up to ensure continuity
if not working;
Remove all system wires connected to the HHC jacks at the top
of the unit and place a volt meter directly across the “24Vdc Out”
(+) and the “COM” (-) jacks, and measure the output. If the icon is
on the display and the 24Vdc output is there (24V ± .5 volts) then
the HHC is operational and the system set up is faulty. Check the
set up. If the loop supply output is still non-operational consult the
factory.
DATALOG WILL NOT EXPORT TO THE SD CARD
Ensure that the internal datalog memory has a datalog loaded
into it (see section 15f vi. Review Datalogs). If there are no stored
datalogs, the HHC will display an error message .
Verify that SD card write protect lock is off.
Ensure that the SD card is fully inserted into the onboard
connector of the HHC.
The SD card may be faulty, change the SD card
In order to ensure compatibility with the majority of manufacturers, the
PTE-2 was developed using a number of different types of SD cards
try using one of these recommended SD cards. (See section 16g)
Refer to the manual and repeat steps required to export data.
If the HHC still displays an error message, consult the factory.
