Measurement & Display
16 segment 2 line LCD displays the following parameters. Some of the parameters are model dependent and are available in only those models.
Normally the display auto scrolls and displays a set of parameter for 10 seconds, but any time the Next key (^) can be pressed to select the next parameter window.

Mains O/V |
Max. Permissible voltage, above this the voltage is treated unhealthy & Generator is started |
270V |
80-300V |
Mains U/V |
Min. permissible voltage, below this the voltage is treated unhealthy & Generator is started |
180V |
80-270V |
Mains Sup Delay |
Time for which the Mains voltage has to be unhealthy (Under or Over voltage as defined above in 1 & 2) before starting the Generator |
10Sec |
1-999Sec |
Mains O/F |
Max. Permissible Mains frequency,above this frequency the Mains is treated unhealthy & Generator is started |
55Hz |
40-65Hz |
Mains U/F |
Min. permissible Mains frequency,below this frequency the Mains is treated unhealthy & Generator is started |
45Hz |
40-65Hz |
Mains Freq Delay |
Time for which the Mains frequency has to be unhealthy (under or over voltage as defined above in 4 & 5) before starting the Generator. |
10 Sec |
1-999 Sec. |
Mains Vol Unbal |
Max. Permissible voltage difference between two phases of mains. Above this the voltage is treated to be unbalanced and Generator is started. |
Disable |
10-100 Disable |
Mains Ph Seq |
Enabled/ Disabled |
Off |
On/ Off |
Phase Seq Delay |
Duration for which the unhealthy phase sequence is acceptable. After this time the mains is treated as unhealthy and the engine is started |
10 Sec |
1-999Sec |
Unbalance Delay |
Duration for which unbalance can be allowed before starting the Generator. This parameter is not available if (7) is set to disabled. |
10Sec |
1-999Sec |
Gen Start Delay |
The starting of generator is delayed by this time after the mains unhealthy timers have expired and the mains contact has been released. This is required in certain applications where immediate generator starting is not required but the mains contactor are to be protected. This timer is automatically reset, if during this duration the mains become healthy for ââ¬ÅMains Restoration Delayââ¬Â (28) |
Disable |
1-999 |
Gen Start Unit |
The generator start delay(11) can be programmed in seconds or minutes. This parameter is not available if (11) is disabled. |
