About the Model 493.07 Converter Box
This section describes how to jumper the Model 493.07 Converter Box to
connect a Series 494 Chassis and other controller types to a hydraulic power
unit (HPU). The converter box converts logic-level signals to and from the
Series 494 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.
Part numbers
The Model 493.07 Converter Box is available in 24 V DC and 115 V AC
versions for specific controllers.
HPUs that require control voltages that are not compatible with the
controller HPU Interface board require a Model 493.07 Converter Box
designed for the correct voltage.
Connecting a 24 V Converter Box to a 115 V AC HPU can cause damage
and improper operation.
Make sure that the voltage marked on the cover of the converter box matches
the required voltage for the HPU.
* Converter box interfaces to controllers manufactured before 1986
require custom cables.
