摘要:PURPOSE:To automatically test auxiliary power sources all together to shorten a testing time by providing a test control part for testing auxiliary power sources at the time of receiving an auxiliary power source test starting instruction and sending back a result and a means for sending the auxiliary power source test starting instructions all together to the test control part. CONSTITUTION:The test control part Tc is provided in correspondence with the individual auxiliary power source to supply base current to a transistor Tr at the time of receiving the test starting instruction and conducts between the collector and emitter of the transistor Tr to operate a relay BT. By the operation of the relay BT, the two contact points bt work to interrupt supply to the auxiliary power source PE from a power source circuit PC and connect the auxiliary power source PE to the ground by way of a discharge resistor R. An auxiliary power source monitoring circuit PESC connected to the discharge resistor R compares a reference voltage obtained by a dividing resistance, etc., inside the auxiliary power source monitoring circuit PESC with a voltage between both terminals of the discharge resistor R, monitors whether the voltage of the auxiliary power source PE is enough or not and sends the result to the test control part TC.
