Control Signals

When the rack system is equipped with Digiplan control modules, the signal connections are made via 8-way jumper cables fitted to a mating connector on each drive motherboard. In these systems it is not normally necessary to make external signal connections to the drives, since all control signals go to the control card motherboard.

Where the rack is equipped with drives only, control connections are made to the two-part connectors on the drive motherboard (see Figure 3). The following list describes the function of each terminal.

PIN 1 - +24v. This is an auxiliary fused output which provides 24 volts unregulated at up to 500mA. If the load is to exceed 250mA, fit an external 2200uF 35v capacitor between this terminal and terminal 8 (0v). Remember to observe the correct polarity.

PIN 2 - Fault. This is a composite output signal which goes high in the event of an overload, short circuit, supply failure or overtemperature fault. It is driven by an open-collector transistor and should therefore be pulled up by an external resistor when the signal is required. The resistor should be returned to a voltage no higher then 30 volts and should not allow more than 15mA to flow when the output is low.
