b.1 Electrical Connections
Figure b-1, 9 pin "D" Connector Pinouts for PSV-D Driver Module.
Important notes:
In general, "D" Connector numbering patterns are standardized. There are, how-
ever, some connectors with nonconforming patterns and the numbering
sequence on your mating connector may or may not coincide with the numbering
sequence shown in our pin configuration table above. It is imperative that you
match the appropriate wires in accordance with the correct sequence regardless
of the particular numbers displayed on your mating connector.
Make sure power is OFF when connecting or disconnecting any cables in the
system.
The power input is protected by a 1600mA M (medium time lag) resettable fuse.
If a shorting condition or polarity reversal occurs, the fuse will cut power to the
valve driver circuit. Disconnect the power to the unit, remove the faulty condi-
tion, and reconnect the power. The fuse will reset once the faulty condition has
been removed.
Use of the PSV-D valve driver in a manner other than that specified in this manu-
al or in writing from Aalborg, may impair the protection provided by the equipment.
