5. Check switch selection
SW1/1 ) Speed Range (see table 4.1)
SW1/2 )
SW1/3
Tachogenerator / VA (see switch options on page 4.1)

6. SW2, 3 and 4 Check Current Calibration.
7. Check all pots are set thus:-
Potentiometers P4, P5, P6, P8, P10, P12 fully anticlockwise.
(Potentiometer P5 will be set to 90% clockwise when the drive is unpacked).
Potentiometers P1, P2 , P3 and P6 mid position.
Potentiometer P11 should be left at the factory set position (approximately midway) until zero
speed adjustment is required.
8. Check auxiliary supply transformer tap is compatible with the auxiliary supply voltage.
9. Check external run contacts are open.
10. Check external set points are all zero.

Although fairly general, the following assumes the system to be a simple speed control drive
and motor.
1. When all the preceding steps are completed the auxiliary power supply can be connected to
terminals A3 and A4, (but do not connect the L1 and L2 main power supply at this stage).
Immediately check that the correct voltage appears between A3 and A4.
2. Now check:-
i) The drive condition indicators - these are 5 LED lamps at the top left corner of the
product. The “Power-On” should be on.
ii) Check that the +24v (nominal) supply at terminal T24 (with respect to T8 or T11) is
between 22 and 30 volts dc.
iii) If a Diagnostic Test Unit (5570) is available, check the ± 15v supplies on switch
positions 1 and 4.
iv) Check the + 10v supply rail:
Switch to diagnostic test point 2 or measure the voltage between terminals T14 (+10v)
and T8 (0v).
v) Check the -10v supply rail:
Switch to diagnostic test point 3 or measure the voltage between terminals T16 (-10v)
and T8 (0v).
Note:- If the supply voltages are incorrect check setting of Auxiliary Supply Selector
Switch.
