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 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.
