Davey Speedman Dual Pump Variable Speed Pump Control System - Manual (Page 42)

42
There are 8 main inputs with the Speedman that control external sensing functions.
All inputs are programmable to suit various applications.
They all require VOLTAGE FREE contacts and as such should NOT HAVE ANY VOLTAGE APPLIED.
• All inputs operate on a CLOSED CONTACT for activation. This contact needs to be made between
the input common and the relevant input. There are three terminals for the input Common to allow for multiple
connections.
You can view which inputs are activated by accessing PUMP DATA LOG menu under the “Digital Input State”
screens. See PUMP DATA LOG for more information.
Each Input can now have inverted logic.
Normally if an input is connected via a switch or sensor between the input common and a programmable input
it is deemed to be ON and the input LED will be illuminated.
With inverted logic when an input is activated the controller will read this as OFF but the input LED will be
illuminated to indicate the actual state of the input. Inverted inputs have a number of uses and the main use
would be to provide fail safe activation of an input. Eg. If an programmable input is set to pause the system
on low level, then a normal input would provide an ON signal to pause the system, should that input be
disconnected or broken the system would not shut down resulting in damage to the pumps. If the input is
inverted the float can be wired to close the input connection for system run & open for system pause. (Fail
Safe)
To invert an input, firstly have the required input on the display, press the Enter button and then press the Up
& Down buttons simultaneously, the Input should now show (INV) on the top line. The change it back complete
the same procedure.
