The MM performs internal tests to ensure that the mains power is safe for
the unit to operate (zero crossing and mains input tests). When these tests
return a negative result the MM generates a fault. This parameter governs
the way the MM handle these tests results; setting 1 makes the MM more
tolerant to the mains power instability while setting 2 disables the errors
altogether.
Note: Setting 2 should only be used temporarily while investigating and
correcting the cause of mains power instability. Running the MM continually
on unstable power can degrade the MM and cause permanent damage to
the unit.
Parameters 110 – 160 are a repeat of their corresponding options and will need to have the same value.
It is the responsibility of the commissioning engineer to ensure that all settings are set in accordance with the
appropriate standards, local codes and practices. If options 110 – 160 are not identical with the parameters 110 –
160, then the MM will go straight to Commissioning Mode and an option/ parameter conflict message will appear.
