AMF Panel

We are offering amf panels, “protogen” is a 3-phase automaticmanual generator controller module that includes protection for gen-sets. Use of advanced micro controller in the design platform provides easy and trouble free control and operation mechanism of gen-sets in case of failure of mains power. Upon failure of mains power (due to faults like loss of power, over voltage, under voltage, phase reversal, phase unbalance etc.), “protogen” initiates “automatic gen-set start cycle” including transfer of load to gen-set by using the generator contactor. As and when the mains power gets restored, the load gets automatically transferred back to the mains line and the gen-set stops after a cool-down time. During the cycles, the gen-set is protected against malfunction. All alarms occurring at abnormal gen-set conditions are computed and displayed either by led or on lcd through alphanumeric messages.
values of overunder voltage, frequency and overload current, cooling-down time are programmable. “protogen” provides forty-five programmable parameters to suit customer’s needs. 1.1. Features

•   1.2 operations “protogen” has two basic operation modes, namely auto mode and manual mode. In auto mode, “protogen” controls the gen-set automatically according to the parameter settings. Two push buttons (“start” and “stop”) have been provided to operate the engine manually (manual mode). auto mode: to enter into the auto mode switch on the automanual switch of the control panel to “auto” position. “auto mode operation.” message will be displayed on the lcd. mains fail: when mains power fail due to any fault in the system, “protogen” initiates an auto-start sequence to start the gen-set. After successful start of the gen-set, the load is transferred from mains to “protogen” automatically. However, in case of phase reversal, “phase reverse message” appears on the lcd for corrective action. starting sequence: crank will be given to the generator. The lcd will display “dg start mode….” message. If the generator starts within the number of attempts set in the program (programming parameter no.8), the load will get shifted to the generator. If the generator does not start within the programmed number of attempts, “fail to start” message will be displayed for corrective action. restoration of load to mains power: when mains supply returns to normal condition, “protogen” will transfer the load automatically from generator to mains after “mains restore time” (programming parameter no.4), through the mains contactor. The generator cool-down time will start thereafter. During the cool-down period the generator will run with out load. manual mode: the “protogen” unit is by default on manual mode when power is on. To enter in manual mode, switch on the “automanual switch” of the control panel to manual position.
  “ manual mode operat.” message will be displayed on the lcd. In manual mode, the gen-set can be started and stopped by means of two push buttons “start” and “stop” on the front panel. The startstop sequence relates to the parameter settings.
