On successful code entry, a screen is displayed to the user to confirm the action to leave the P450
IHEM from the ZigBee network and therefore stop communication with the Electricity Meter.

13.3.3.1 Diagnostics 24-hour lock out
The diagnostics screen supports a code entry mechanism which will stop misuse of the code entry. If
the user again attempts to enter 3 invalid codes, then the P450 IHEM will disable access to the code
entry screen for 24 hours.
The lock out will be displayed to the meter in a visual message stating:
‘
Code entry is disabled Try
again in X hours
X minutes’.
This can be seen in the following example.
At the end of the 24-hour period the lock out mechanism is reset.

13.3.4 Demand threshold
Selecting the Demand Threshold button navigates the user to the second level menu where the user
can configure the Demand Threshold and Demand Alert settings for the P450 IHEM operation.
The demand threshold settings are used to manage how the demand energy indicator manages
instantaneous usage.
The demand alert setting allows the user to enable an audio and visual alert to identify that the
instantaneous usage has risen above the high threshold value.
The following section details the configuration and management of both functions.
