    摘要： Apparatus is provided for activating a plurality of groups of electrical loads, such as electrical detonators used in blasting, after respective time delays. The apparatus comprises a master control unit (10) which generates master control signals to initiate timing out of delay devices (16) associated with each load. The apparatus further includes several auxiliary control units (12) which are connectable to the master control unit. Each auxiliary control unit is adapted to control a respective group of remote electrical delay devices (16) with associated electrical loads. Each auxiliary control unit includes local control means for generating local control signals from the master control signals which are synchronised with the local control signals of other auxiliary control units, for initiating operation of the delay devices, so that a large blast can be carried out in a perfectly synchronised manner. The master control unit may transmit master programming signals to the auxiliary control units, which each program the electrical delay devices of their respective group. Synchronisation of the local control signals can be achieved in a number of different ways. A method of activating a plurality of groups of electrical loads is also described.

    摘要： A testing circuit is provided for testing the operability both of a load (30) and of a capacitor (26) incorporated into a main detonator circuit and arranged to discharge into the load for detonation thereof. A test pulse is generated at a central controller to which a ring of detonators is connected on a harness. The test pulse is routed via the harness for storage in the capacitor. A controlled switch (44) is operated to allow the capacitor to discharge into the load. A transistor (52) is operated by the discharge signal, the transistor having an output for delivering a discharge value signal (56) in response to the discharge signal remaining above or falling below a threshold value. The discharge value signal is latched and is in turn used to inhibit a local oscillator (66). The inhibited signal from the oscillator is routed back to the controller so as to indicate a fault either in the capacitor (26) or in the load (30).
