500and600seriesclosecoupledpumps
Details on the use, operation, maintenance and spare parts for the 500 and 600 series close coupled pumps can be found in the
accompanying manual PB 0279.
Trio cose coupled pump operating instructions
Trio close coupled pumps combine a pumphead, motor/ gearbox and integral inverter into a robust IP55 pump.
500 and 600 series Trio close coupled pumps
This equipment contains hazardous voltages (at mains potential) inside the pump. If access is required, turn
the power off and wait one minute so that the dc-link capacitors can discharge. Some parameter settings
can start the motor automatically after a mains failure. The Trio inverter is not to be used as an emergency
stop mechanism, a circuit breaker must be used.
Wiringconnectiondetails
Remove the four M4 cross head screws on the Trio’s cover to access the electrical terminals (see Fig. 2).
Note: A ‘drip loop’ is recommended when connecting the mains and control cables (see Fig. 1).
Fig. 1 Connecting mains cables and control cable with a drip loop.
The printed circuit board is particularly sensitive to static electricity. For this reason, avoid touching the
boards or components with your hands or metal objects.

4
Mainscableconnections
Ensure that the power source supplies the correct voltage and is designed for the rated current. Use a circuit-breaker with a 10A
current rating between the power supply and Trio. Use Class 1 60/75°C copper wire only with a cross sectional area of 1mm. If
crimp terminals are used they must be insulated. If crimps are not used, the strip length must not exceed 5mm. Feed the power
cable into the inverter via the gland hole nearest to the motor shaft using a PG16 gland. Connect the power leads to terminals L1,
L2 and the separate earth. Use a 4-5mm cross head screwdriver to tighten the terminal screws.

Fig 2. Electrical connection drawing
Ensure that the following tightening torques are used: Access cover retaining screws:
2.5Nm, Gland hole covers: 1.0Nm, Mains connector screws: 1.0Nm, Control connector PL700: 0.4Nm.
Check the supply voltage is correct for the inverter used by referring to the rating label.
Controlcableconnections
The control and power supply cables (max 1mm diameter) must be laid separately. They must not be fed
through the same cable conduit/ trunking.
Use screened cable for the control lead.
Feed the control cable into the inverter via the appropriate gland hole (see Fig. 2). Connect the control wires in accordance with the
information in Fig. 3 and 4 (also see Fig. 1).
IMPORTANT: A wire link will have been factory fitted between control terminals 5 (DIN1) and 1 (P10+) to enable the Trio to
operate when control potentiometer R314 is used. The wire link must be removed when operation via a run/
stop switch is required.
Note that the optional potentiometer fitted as an analogue set point shown in Fig. 3 assumes that jumper JP304 is connecting 0V
(pin 2) to AIN- (pin 4). Also, P15+ can be used as an alternative to P10+ for the digital inputs.

Refit the cover and tighten the four securing screws.
OperatingInformation
The equipment must not be switched on until after its cover has been fitted and the cover screws have been
tightened to the correct torque. (see fig 2.) When using the external analogue control the jumpers (Fig 2) must
be correctly set and the analogue signal type selected (PO23) before enabling the analogue input with P006.
If this is not done, the motor may start without warning.
The inverter does not have a mains power switch and is therefore live when the mains supply is connected.
When supplied, the inverter has a frequency setpoint range of between 5Hz and 50Hz.
BasicOperation
1. Using the internal potentiometer
(a) The Trio is pre-set for forward rotation. For reverse rotation move the link from DIN1 (pin 5) and P10+ (pin 1) to DIN2 (pin
6) and P10+ (pin 1) on the control cable connector (see Figs. 2 and 3).
(b) Apply mains power. The green and yellow LEDs will illuminate to show that power is applied. Turn potentiometer R314
(accessed by removing the right hand gland hole cover (see Fig. 2) fully counter-clockwise, otherwise the Trio cannot be
started.
(c) Turn the potentiometer clockwise until the yellow LED extinguishes. This indicates that power is now applied to the motor.
Continue turning clockwise to increase the speed of the motor.
(d) Turn the potentiometer counter-clockwise to reduce the speed of the motor. Turning the potentiometer fully counter-
clockwise will slow the motor to a complete stop and both LEDs will be illuminated (STANDBY mode).

4. Using external analogue control
(a) Remove the four M5 cross-head screws on the inverter’s cover to access the electrical terminals (see Fig.2).
(b) Connect a 4.7 kW potentiometer to the control terminals as shown in Fig. 3 or apply a 0 - 10 V signal between pin 2 (0V) and
pin 3 (AIN+). In both cases, position jumper JP304 to connect 0V to AIN-.
(c) Ensure that a link is fitted between pin 5 (DIN1) and pin 1 (P10+).
(d) Check that voltage input is selected by ensuring that the jumper is fitted to JP301 (Fig 2).
(e) Refit the cover, tighten the cover screws to the correct torque and then apply mains power to the inverter.
(f) Turn the external potentiometer (or adjust the analogue control voltage) until the desired frequency is achieved. The unit
will not switch on until a minimum of 2 V has been applied.
(g) Turning the potentiometer counter-clockwise or adjusting the analogue control voltage below 2 V will slow the motor to a
stop.
Note: The frequency set by the external voltage is added to the frequency set by the internal potentiometer. A run/stop switch can
be used to start and stop the motor, or the direction of rotation can be changed by connecting the link to DIN2 instead of
DIN1.
5. Remote control using pre-set frequencies
For basic startup configuration, proceed as follows:
(a) Remove the four M5 cross head screws on the inverter’s cover to access the electrical terminals (see Fig. 2 and 3).
(b) Remove the link between pin 5 (DIN1) and pin 1 (P10+).
(c) Connect pin 5 (DIN1) pin 1 (P10+) via a simple on/off switch. This sets up the inverter for clockwise rotation (default). If
counter-clockwise operation is required, connect a switch between control terminals 6 and 1.
(d) Connect the OPm2 and set parameter P005 to the desired frequency setpoint.
(e) Set parameter P006 to 000 to specify digital setpoint.
(f) Set the external on/off switch to on. The inverter will now run at the frequency set by P005.
6. Remote control using RS485
Up to 31 Trios can be controlled via a 2-wire bi-directional RS485 serial link connected to the control terminals (see Fig 2 and
3), or the OPm2 socket on the side of the Trio. Baud rate 1200 to 19200 (set by parameter P092), serial line time-out 0-240
seconds (parameter P093).
Safety
Minimum speed running
The minimum safe speed to run the TRIO is 5Hz.
Fault finding
If the motor does not start up check the LEDs on the side of the inverter:
LED State TRIO Status
Green Yellow
ON ON Mains power on, inverter not running (STANDBY)
ON OFF Inverter running, as control commands (ON)
Flashing Flashing Current limit warning
Flashing ON Inverter over temperature
ON Flashing Motor over temperature
OFF ON Other fault (e.g. tripped)
OFF Flashing Mains under voltage
OFF OFF Mains supply fault (e.g. faulty external switch)
If a fault occurs: switch off, disconnect and then reconnect the power, and then switch on again. Switch off if the fault condition
persists. Trips can be reset by connecting a switch to DIN3 (Fig. 2 and 3).
If a warning occurs: switch off, disconnect and reconnect the power and then switch on again. If the fault/warning persists, further
investigation requires an OPm2 or a serial link connection.
If the OPm2 display shows a fault code, refer to Fault Codes.
