5.1 Program Functions
P04 Battery Voltage Lower Limit
P05 Battery Voltage Upper Limit
If the battery voltage drops below the defined Battery Voltage Lower Limit, an alarm occurs. The
message bAT1 (Low battery) appears on the display. Similarly, if the battery voltage exceeds the
defined Battery Voltage Upper Limit (P05), an alarm occurs. The message bAT3 (High Battery)
appears on the display.
P02 Speed Lower Limit
P03 Speed Upper Limit
P33 Speed Fault Control Delay
A fault will be reported if the alternator output frequency goes outside the window defined by the
upper and lower limits for more than the time defined as the Speed Fault Control Delay (P33). The
fault will only occur after the engine has been running for the period defined as the Control on
Delay (P31). This failure immediately stops the generating set without Engine Cooling Time (P34)
P00 Alternator Voltage Lower Limit
P01 Alternator Voltage Upper Limit
P11 Phase Type Selection
P32 Alternator Voltage Fault Control Delay
A fault will be reported if the alternator output voltage goes outside the window defined by the
upper and lower limits for more than the time defined as the Alternator voltage fault control delay
(P32). The fault will only occur after the engine has been running for the period defined as the
Control on Delay (P31). This failure immediately stops the generating set, without Engine Cooling
Time (P34).
There are four possible system types:
P11= 1
Single phase system. Set parameters Alternator Voltage Lower Limit (P00) and
Alternator Voltage Upper Limit (P01) as line to neutral voltage
P11= 2 Single phase three wire with 180 degree phase shift between the phases.
P11= 3 Three phase four wire. Parameters Alternator Voltage Lower Limit (P00) and
Alternator Voltage Upper Limit (P01) are line to line voltage
P11= 4 Series delta three phase four wire. A delta configuration where neutral is between
two phases. Parameters Alternator Voltage Lower Limit (P00) and Alternator
Voltage Upper Limit (P01) are line to line voltage
5.1.1 Alternator Voltage
5.1.2 Alternator Frequency
5.1.3 Battery Voltage
P07 Periodic Maintenance Hour Set Value
P08 Periodic Maintenance Hour Reset
To ensure reliability, the engine must be serviced at regular intervals. The unit can be set to
indicate when a service is due. Set Periodic Maintenance Hour Set Value (P07) to the number of
running hours between services. Use Periodic Maintenace Hour Reset (P08) to reset the hours
5.1.5 Maintenance Indication
An alarm occurs if the load current exceeds the load current limit for more than 5 seconds after the
period defined by the Control on Delay (P31). The message ocr (Over Current) appears on the
display.
5.1.4 Over Current Limit (P06)
