• Any Pump Running
Any pump running will activate the relay.
• No Flow Shutdown
The No Flow Shutdown action is active.
• VSD Fault
Output is on when the VSD is being tested or the VSD has shutdown.
• Pressure Trip 1
When the system pressure reaches the nominated Pressure Trip 1 Low and High, this relay will
energise or de-energise. See Pressure Trip in SETTINGS.
• Pressure Trip 2
When the system pressure reaches the nominated Pressure Trip 2 Low and High, this relay will
energise or de-energise. See Pressure Trip in SETTINGS.
• Alternate Trip
Each time the system shuts down the energized state of the relay will change. E.g. If the relay on one
cycle is closed during operation then the next cycle this relay will be open.
The relay will change on the following: - Low Pressure Shutdown, High Pressure Shutdown, No Flow
Shutdown and VSD Shutdown.
• Flow Trip
When the system flow reaches the nominated Flow Trip points Low or High, this relay will energise or
de-energise. See Flow Trip in SETTINGS.
• Aux Outputs 1 - 3
Any output can be set to be an auxiliary output. Setting an output to become an auxiliary output allows
the Speedman to use an input to turn on a Digital Output. To do this the input has to be set up to be
an Auxiliary input. There are three auxiliary functions available.
Aux Input 1 operates Aux Output 1
Aux Input 2 operates Aux Output 2
Aux Input 2 operates Aux Output 3
• Set Point Output 1-8 (SP 1-8 Output)
Outputs are activated depending on which set point is the current set point. The current Set Point can
be set by ether configuring an input or setting a time of day event.
* RELAY RATINGS
The relays are rated at 5 amp 250VAC. Consideration of inrush current, inductive loads and cycling
must be taken into account when applying current to these relays.
