Copy TOA parameters
It is possible to load TOA parameters to the memory device AEC-PM2 and copy them to other TOA
devices.
Loading memory device
1.
Remove the upper part of the TOA housing (see section "Connecting the TOA and putting it
into operation", page 6).
2.
Insert the AEC-PM2 memory device into the TOA connector
. Ensure correct polarity (see
section "Wiring and Connection", page 4)!
3.
Connect the OPA-S operating device to the TOA connector
(see section "Wiring and Connection", page 4).
The measured temperature is displayed.
4.
Press the "UP" and "DOWN" keys simultaneously for at least 3 seconds and wait until "Code" is displayed.
5.
Use the "UP" or "DOWN" keys to set the password "0009" and confirm with the "RIGHT" key.
6.
Confirm the "IP SEL" display with the "RIGHT" key. The first parameter will be displayed.
7.
Use the "UP" or "DOWN" keys to switch to the "IP 05" parameter. After pressing the "RIGHT" key, use the "UP"
or "DOWN" keys to set the parameter to "1". Confirm the setting with the "RIGHT" key.
8.
After pressing the left "ON/OFF" key twice, the parameters are copied from the TOA to the AEC-PM2.
The red "Data" LED of the AEC-PM2 lights up for 5 seconds after successful copying and parameter "IP 05" is set
to 0. If copying has failed, the red "Data" LED flashes for 5 seconds and parameter "IP 05" is set to 7.
9.
Remove the AEC-PM2 memory device and the OPA-S operator interface and close the TOA housing (see section
"Connecting the TOA and putting it into operation", page 6).
Copy parameters to other TOA devices
1.
Remove the upper part of the TOA housing (see section Connecting the TOA and putting it into operation, page
5).
2.
Insert the AEC-PM2 memory device into the TOA connector P7. Ensure correct polarity (see section "Wiring and
Connection", page 4)!
3.
After pressing the "Copy" key on the AEC-PM2, the parameters are copied from the AEC-PM2 to the TOA.
The red "Data" LED of the AEC-PM2 lights up for 5 seconds after a successful copy process. If copying has failed,
the red "Data" LED flashes for 5 seconds.
4.
Remove the AEC-PM2 memory device and close the TOA housing (see section "Connecting the TOA and putting it
into operation", page 6).
