noise in the region of the device. If the device continuously
resets itself, contact your local distributor.
Device Fault Alarm
The PowerSmart Socket PQM provides a global "DEVICE
FAULT" event flag that is asserted all the time while one of
the diagnostic events exists. It can be monitored via a
setpoint (see
Using Control Setpoints in Chapter 5) to give a
fault indication through a relay output. If the alarm relay is
programmed for failsafe mode using inverting polarity, then
its normally closed contacts will be open if either the meter
looses power or a device fault occurs.
Meter Security
The PowerSmart Socket PQM provides 3-level password
security for protecting meter setups and accumulated data
from unauthorized changes. Meter readings are not software
protected.
Access to particular setup and control items is granted
depending on the security level of the password you entered.
The passwords can be 1 to 8 digits long.
The PowerSmart Socket PQM is also provided with the
security jumper located on the main CPU board under the
meter cover. Removing the security jumper grants a full
access to the meter settings and permits clearing the billing
data registers and billing data profile files (see
Clearing Billing
Data ).
The following table shows the meter security levels and user
access rights.

factory set passwords as fast as possible. See
