Note: Plug/Socket designation refers to the pins of the connector.
3.10.1 Inputs
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.
3.11 Connect the cooling-water hoses
Water only flows if the pump is running or for about 10 seconds when the pump is first energised. You may
damage your water circulation system if it cannot tolerate a no flow condition.
Note: For optimum water-cooling, ensure that your cooling-water supply complies with Section 2 and that the dry
pump is not connected in series with any other equipment.
Connect the cooling-water supply as follows:
1. Connect your supply and return hoses to the pump.
2. Turn on the cooling-water supply.
3. Energise the system to ensure water flows through the pump.
