Installation
3.11 Connect to your control equipment
Do not connect voltages greater than 30 V to the EPX interface control. If you do, the interface control will not
comply with the low voltage safety directive and the equipment may be damaged.
The pump may be connected to your control equipment through the Tool Interface connector (TIM). The TIM is
supplied with a protective plastic cap fitted. Remove this before connecting the mating connector. Several different
tool interfaces are available. The label next to the tool connector identifies which TIM is fitted, refer to Table 12 to
identify the tool connectors and mating tool connector kits available (not supplied with the pump).
Note: Plug/Socket designation refers to the pins of the connector.
3.11.1 Inputs
Refer to Table 13 for a definition of the input signals to the pump system.
Notes: 1. Volt free contacts sensed at 24 V / 5 mA, these inputs should not be linked together.
2. Voltage inputs accept AC or DC voltage (except SPI pins 15 and 16), between 15 V and 24 V selects the
input as active, below 5 V selects inactive.
3. To ensure correct pump operation, at least 10 seconds must be allowed between successive operations
of the input signals.
Tool interface control signals are for control purposes only and should not be relied upon for safety
critical functions.
