Introduction GTR-20 is a full digitized controller equipped with all basic functions such as display error message, detect input, measured signal and generator status. When the error occurred, GTR-20 shuts down the engine, diagnosis can be known easily by reading LCD panel information. Parameters can be adjusted from front panel in accordance with any special requirement. Operating DC power range is from 8 to 38 volts, and low power consumption in standby mode which suitable for small battery charger.

In table “1” means [Enable], “0” means [Disable]. The setting can be calculated by adding all related bit multiplies its weighted value. The setting of disable “Low frequency” & “L.O.P” is 128 * 1 + 64 * 1 + 32 * 0 + 16 * 1 + 8 * 1 + 4 * 1 + 2 * 1 + 1 * 0 = 222 4.5.9 Low frequency setting Range: 42～61 Hz Default: 54 Hz Description: When frequency is under this setting, system indicates a low frequency failure.
