Appendix B
Model 493.07 Converter Box
This section describes how to jumper the Model 493.07 Converter Box to
connect the Model 493.10 chassis and other controller types to a hydraulic power
unit (HPU). The Converter Box converts logic-level signals to and from the
Model 493.10 chassis to relay signals used by the HPU pump.
For pumps that are 24 V PLC compliant, the Converter Box is not needed. This
includes all Series 505 HPUs and 506.52-.92 HPUs.
You must have the Model 493.07 Converter Box designed for the correct
voltage before installation. Connecting a 24 V Converter Box to a 115 V AC
HPU causes improper operation.
Be sure that the voltage marked on the cover of the Converter Box matches the
required voltage for the HPU.
The following figure shows the main components of the 493.07 Converter Box,
including connectors and jumpers.
If the converter box remains connected to a 120 volt HPU, voltage will be
present.
Failure to disconnect cables could expose the operator to dangerous
voltages.
Disconnect all cables from the Model 493.07 Converter Box before removing
Jumper configurations As shipped, the HPU interface on the Model 493.07 Converter Box is compatible
with Model 458.10/.20, 490.01, 493.xx, and 497.05 components.
The Model 493.07 Converter Box may be connected to other controllers (as
shown in the following table) using a “Y” cable.
