2.1 POWER SUPPLY WARNING
These products require a +5V DC power supply with a tolerance of +/-10%(+/-0.5V). For best
printing quality, it should regulated to better than +/-5%(0.25V). The current required varies with
the printing density and it is vitally important for correct initialisation and operation that the supply
can deliver sudden peak currents during operation and at start up of 5A. It is particularly important
that the initial rise-time of the supply is short enough to give a valid reset to the controller (eg 10ms
for 10% to 90%). The mean current will typically be 2A.
Note also that these products have split 5V supplies to the mechanism and controller and it is
strongly recommended that these be fed from separate regulators. The power to the controller
must
then be applied first, and removed last, if there is a significant difference in timing. The controller
supply current will be a maximum of 30mA, but the mechanism supply must be capable of 5A.
In considering the power supply arrangements, attention should be paid to the wiring and
connections, as significant voltage drops may otherwise occur. The printing performance and
reliability may be seriously affected by inadequate supply arrangements.
2.2 POWER SUPPLY TEASING
Momentary interruptions to, or reductions in the voltage of the power supply to the controller can
result in a fault condition from which it cannot recover until power is completely removed and
correctly restored. Under these conditions, the printer solenoids may be energised continuously
and burned out in a matter of seconds. The user must ensure that the supply will not be teased in
this way, or else protect the system from such effects.
The power supply must not be taken above 6V (5V +20%), or reversed, even under transient
conditions. Particular attention should be paid to the power arrangements in vehicle or battery-
operated applications, where load dump transients or reversal of replaceable batteries might occur.
Able Systems have many years' experience of the application of these products, and advice will be
freely given on request. These notes may seem severe, but what few problems occur are almost
invariably related to power supply faults.
