This controller can perform control functions for most Dual Pump pumping applications. It is more than likely that the
control parameters have already been set up for your particular application, however, hereunder you will nd details
of the setup and conguration options.
DIP
Switch
Position Function
1/2 O󰀨/O󰀨 Mode A: Standard typical oat switch conguration (Start,Stop and High Level). No Low Level
O󰀨/On Mode B: Standard conguration plus low level (Start,Stop and High Level).
On/O󰀨 Mode C: Standard conguration plus Prime Loss enabled, on Low Level (Input 1)
On/On Mode D: Pressure Pumping conguration (Lead, Lag and Low Pressure)
3 O󰀨 Operating Pump alternates each time a pump start is triggered, or after 30 minutes continuous running.
On Operating Pump alternates after 6 hours continuous running.
4O󰀨 Anti-seize Timer disabled
On Anti-seize Timer 6 seconds every 7 days enabled
5O󰀨 When placed in Manual Mode, pump remains in Manual Mode
On When placed in Manual Mode after 5 minutes the pump will revert to Auto
6 O󰀨 High Level Alarm automatically resets upon open circuit of high level input. High Level alarm
has 15 minute delay.
On High Level Alarm can only be reset manually. High Level Alarm has 5 minute delay.
Mode A: Standard Conguration
Start/Stop/High Level operation. When the Pump Start input is closed contact (triggered), the Duty Pump
will be turned on. The pump will remain on until both the Pump Start and Pump Stop Inputs have turned o󰀨
(Open Circuited). Upon High Level, both pumps will run until the Pump Stop Input turns o󰀨.
Input Function
Input 1 Low Level
Input 2 Pump Stop
Input 3 Pump Start
Input 4 High Level
Mode B: Standard Conguration plus Low Level Alarm
As per Mode A, except it has an active Low Level input. The Low Level input must be closed, for Pump Start and
Pump Stop inputs to function. The High Level input however, will still override the Low Level and run both pumps.
Input functions are as follows:
OPERATION
In addition to this, there is a maximum idle timer, which will trigger a Pump Start condition, if either pump has not run
for 4 hours, and the Stop Float Contacts are closed. The pump will continue to run until the Stop Float Contacts open.
Input functions are as follows:
There are 6 DIP switches located on the lower side of the control module, which allows for selecting “mode” and
“feature”options, as per the following table:
Input Function
Input 1 Standby Start
Input 2 Pump Stop
Input 3 Pump Start
Input 4 High Level

5
The basic logic on which a High or Low Level Alarm is determined, is set out in the Table below:
If there is a Low Level Alarm, then both Pumps will be locked out until the alarm is manually reset. This lockout will only
be over ridden upon a High Level condition where both the Pump Start and High level inputs are closed.
Note that after a High level is triggered, the pumps will both run until the Pump Start and Stop inputs are opened
Mode C: Standard Conguration plus Prime Loss
Mode D: Pressure Pumping Conguration
Typical Operation Mode D:
As per Mode A, except Input 1 is connected to a prime loss/ow switch. If at any stage, after Pump Start, or whilst a
pump is running, the Prime Loss input opens, for a continuous 2 minute period, a fault is immediately triggered for that
pump and duty alternates. Input functions are as follows:
Duty Pump: Lead Pump
Standby Pump: Lag Pump
Input functions are as follows:
• Pressure drops to 400kPa: Lead (for this cycle) Pump cuts in.
• Pressure increases and Pump cuts out.
• Cycle continues with duty (Lead and Lag) alternating between the two pumps.
• If pressure continues to drop to 350kPa, the Lag Pump will cut in and remain running until Lead Pressure
Switch opens circuit. Then duty alternates.
• No faults are logged against the Lead Pump if the Lag Pump starts.
• The controller has inbuilt timers for “Delayed” Start and Stop to obviate pump chatter. Upon Input 1 contact
closure, the pump will not start (delay start) for 1 second and will not stop (minimum run time) for 10 seconds
(or 11 seconds from close of Input contacts). This “run on” occurs even if Lead Pressure switch opens circuit
during this initial period. If however run time exceeds 11 seconds, the pump will stop immediately upon “Open
Circuit” occurring.
• If the Lead Pressure Switch input closes circuit as well as he Low Pressure Switch input, both pumps will be
turned on and the Low Pressure Timer will begin counting. If this condition exists for a period of 60 seconds,
then both pumps are shut down and the system signals a level alarm. This would be typical of a Loss of Prime,
or Burst main situation.
• Pressure switches are normally Closed and Opened on High Pressure.
• Prime Loss functions as per mode Mode C.

In pressure pump mode some of the optional features are disabled, including maximum run alternation, anti-seize
and maximum idle timers
In order to activate current loop mode the enclosure must be opened and jumper J10 moved to the “current loop
enabled” position (as shown in the following picture). By selecting current loop input mode the pump start input can
be connected to a 4-20mA loop powered pressure transducer. The pump start, stop and high level signals can then
desired. The start, stop and high level current set points will be pre-programmed into the software and therefore cannot
be adjusted. The levels for a 0-4m transducer are Stop= 300mm, Start= 600mm and High= 1000mm.
Maximum Run and Alternation Mode
controller will automatically alternate pump duty if a pump has been running continuously for 30 minutes (maximum
run timer) Setting this DIP Switch to “On” will cause the controller to operate in “Circulation Mode” where duty will only
alternate once the pump has run for 6 hours of accumulated time.
Anti-Seize Timer
With DIP Switch 4 set to “On”, the Anti-seize timer will automatically run the pumps for 6 seconds, every 7 days. This
pump operation will completely override all inputs including the low level (if enabled). This feature will only run pumps
that are set in Auto. This “Pump Run”, will alternate between Pump 1 and Pump 2. A pump that has been-locked out
due to a fault will not run.
Manual Mode Timeout
With DIP Switch 5 set to “On” the pump will only remain in Manual Mode for 5 minutes, after which time, it automatically
reverts to Auto.
High Level Alarm Reset
The controller will also use the alternate High Level Alarm Delay. Typically used for Storm Water applications. High
Level Alarm delay in this mode is 15 minutes. Setting this DIP Switch to “On”, will cause the High level Alarm to
remain active until the controller is reset. The High Level Alarm will use the standard High Level Alarm activation delay.
Typically used for Sewerage applications. High Level Alarm delay in this mode is 5 minutes.
Audible and Visual Alarm Test
By pressing the Mute/Reset button on the Keypad continuously for a period of 5 seconds, the Strobe, Siren and
indicator Lights will be powered up for inspection.
Fault Reset
To reset all faults on the controller, press and old the Mute/Reset button on the Keypad continuously for a period of 3
seconds until an acknowledgment beep is heard.
Pump Fault
A Pump Fault is indicated for two types of faults. A Thermal Overload will be indicated by way of a steady Fault
fault light slowly.
Level Alarms
A High Level Alarm is indicated by way of a steady Level Alarm Indicator Light.
A Low Level/Low pressure Alarm is indicated by way of a Flashing Level Alarm Light.
Auto Silencing Alarm Feature
The audible Alarm is programmed to sound for 5 minutes continuously, unless muted and will thereafter automatically

Relay is designated for monitoring of levels of conductive liquids with possibility of functions: PUMP UP
or PUMP DOWN. To prevent polarization and liquid electrolysis of liquid, and undesirable oxidation of
measuring probes, alternating current is used. For measuring use three measuring probes: H- upper level,
D- lower level, C - common probe. In case you use a tank made of a conductive material, you can use
it as probe C. In case you require monitoring of one level only, it is neccessary to connect inputs H and
D and connect them to one probe - in this case sensitivity is lowered by half (2.5... 50kΩ). Probe C can
be connected with a protective wire of supply system (PE). To prevent undesirable switching out output
contacts by various inuences (sediment on probes, humidity...) it is possible to set sensitivity of the device
according to conductivity of monitored liguid (corresponding to“resistance”of liquid) range 5 up to 100kΩ.
To reduce infuences of undesirable switching of output contacts by liquid gorgle in tanks, it is possible to set
delay of output reaction 0.5 - 10s.

To reduce infuences of undesirable switching of output contacts by liquid gorgle in tanks, it is possible to set
delay of output reaction 0.5 - 10s.
