Article no.: 5081200002 2022_10_17 Subject to technical change! Errors excepted.
If the HCA e2 is removed within 1 hour after its initial installation on the heat conductor, the display shows "OPEN"
(see 5.3). By re-install the device within this mounting time frame, then "CONFIG / CON FF" appears again on the
display (see 5.1 and 9.1) and the standard display cycle continues.
Repeated removing and re-installing can be done within the mounting time frame several times; but the mounting
time frame is not extended.
Only at the end of the mounting time frame for installation (waiting period), the measurement function of HCA e2
is enabled!
If the HCA e2 is removed after the end of the mounting time frame for installation from the heat conductor or
fitted again after the end of the mounting time frame, the display shows "OPEN C" in the display cycle (see 5.3).
Here manipulation is suspected. The "OPEN C" hint persists after re-install the HCA e2 and will appear in the display
cycle.
By using the costumer software ”Device Monitor” (register parameterization – reset removal detection -) the hint
“OPEN C” can be reset.
The display briefly shows "
STBY
", then "
CONFIG
/
CONF FF
" appears and the device continue with recording data by
displaying standard display cycle.
If the reset is performed on the removed HCA e2, the "
STBY
" appears on the display and will persist until the re-
install of the device. After re-install the display briefly shows “
CONFIG
/
CONF FF
" and the device continue with
recording data by displaying standard display cycle.
