How to reset the product after a power loss or when the power has been unexpectedly removed
The settings for the product are retained in memory prior to the power loss or de-energizing of the product.
The output condition is also recoverable to that prior to the power loss or de-energizing. However, this may
change depending on the operating environment. Therefore, check the safety of the whole installation before
operating the product.
If the installation is using accurate control, wait until the product has warmed up (approximately 10 to 15
minutes) before operation.
