Notes:
1. The Comm. Authorization is the register to which the master software would be required to write the correct Comm. Password before
it’s allowed to perform any Modbus Read/Write operations with the PMC-230, if the MBPW (Modbus Password) register is enabled. If
the Comm. Password is correct, the master software will be able to communicate with the same PMC-230 continually until there is a
period of inactivity of 60 seconds or longer. When this happens, the master software will have to write to the Comm. Authorization
register again to re-gain access to the PMC-230. If an incorrect Comm. Password has been written to the Comm. Authorization register
for 3 consecutive times, Modbus access will be locked out for approximately 15 minutes.
2. There are two ways to calculate THD:
THDf:
where I
1
represents the amplitude of the fundamental component and I
n
represents the amplitude of the n
th
harmonic.
THDr:
where the denominator represents the total RMS value and the numerator represents the RMS value of the harmonics from 2
nd
to 8
th
.
3. The Self-Read Time applies to the Max. Demand Log and supports the following three options:
•
A zero value means that the Self-Read will take place at 00:00 of the first day of each month.
•
A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read Time = (Day x
100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00
pm on the 15th day of each month.
•
A 0xFFFF value means the automatic self-read operation is disabled and replaced with manual operation.
4. The Monthly Energy Log Self-Read Time supports the following options:
•
A Zero value means that the Self-Read will take place at 00:00 of the first day of each month,
•
A non-zero value means that the Self-Read will take place at a specific time and day based on the formula: Self-Read Time = (Day x
100 + Hour) where 0 ≤ Hour ≤ 23 and 1 ≤ Day ≤ 28. For example, the value 1512 means that the Self-Read will take place at 12:00
pm on the 15th day of each month.
5. Under Auto-Scroll mode, the kWh/kvarh Imp./Exp. and kVAh as well as kWh Imp./Exp. per Tariff are displayed sequentially in 4 seconds
interval.
6. The MBPW register is disabled by default and should be enabled if communication security is required.
