TOA Configuration
The OPA-S operating/programming unit is used for configuration. It can also be used to display the
measured values.
The TOA password-protected parameters (see section "TOA Parameters", page 8) can be set
directly on the device during operation through the OPA-S operating units. The OPA-S operating
unit must be connected to the TOA connector P6 to adjust the parameters. This connection must
not be disconnected earlier than two seconds after the last keystroke on the OPA-S.
If several TOA-T101 units are to be operated with the same settings, prepared parameters can be quickly copied to the
individual units using the memory device AEC-PM2 (see section "Copy TOA parameters", page 9).
Change parameter settings
The TOA-T101 is delivered with a preset temperature limits of 35°C / 30°C (95 °F / 86 °F).
Adjustments can be made to the settings for special requirements and customer requests.
1.
Remove the upper part of the TOA housing (see section "Connecting the TOA and putting it into operation", page
6).
2.
Connect the OPA-S operating device to the connector P6 (see section "Wiring and Connection", page 4).
The measured temperature is displayed.
3.
Press the "UP" and "DOWN" keys simultaneously for at least 3 seconds and wait until "Code" is displayed.
4.
Use the "UP" and "DOWN" keys to set the password "0009" and confirm with the "RIGHT" key.
5.
Confirm the "IP SEL" display with the "RIGHT" key. The first parameter is displayed.
6.
Change to the parameter "IP 03" with the "UP" or "DOWN" keys. After pressing the "RIGHT" key, the parameter
"Switching OFF temperature limit" can be adjusted with the "UP" or "DOWN" keys. Confirm the setting with the
"RIGHT" key.
7.
Use the "UP" or "DOWN" keys to switch to the "IP 04" parameter. After pressing the "RIGHT" key, the parameter
"Switching ON temperature limit" can be adjusted with the "UP" or "DOWN" keys. Confirm the setting with the
"RIGHT" key.
8.
Complete the parameter setting by pressing the left "ON/OFF" key twice. The measured temperature is
displayed.
Important
The TOA can only apply the new settings correctly, if the parameter setting is completed with the left "ON/OFF"
key!
Detailed information to the OPA-S can be found on the website
product page under "Downloads".
