611-A Power Infeed Module(I/R and UE) Start Up Procedure
Caution: During this procedure High Voltages will be present. Power must be removed from the
drive unit (I/R or UE Module) before connecting or disconnecting the P600, M600 DC Bus bars,
power connector X181 or equipment bus ribbon cable X351. THE DC BUS VOLTAGE ACROSS BUS
BARS P600 AND M600 CAN TAKE UP TO 5 MINUTES TO DISCHARGE TO A SAFE LEVEL AFTER LINE
POWER IS REMOVED. Refer to the Interface connections drawing for terminal locations etc.
which are mentioned in the following procedure. Terminal X161.48 must always be disconnected
at least 10 ms before power down.
A)
Be sure power is off and the DC Bus is fully discharged.
Disconnect the P600/M600 DC Bus Bars,
Connector X181, Equipment Bus Ribbon Cable X351, Enable Interface connectors X121 and X161. Check
input power connections on Power Transformer, Line Reactor or filter module, External Fusing and I/R
Module. Check machine and modules for proper grounding and transformer neutral connections.
B)
Check DIP Switch settings on top of the I/R Module. Factory setting is Bits 1 through 5 all in the off
position and Bit 6 in the on position. Caution: some settings depend on line voltage!
C) Power-up
, Check line voltage across U1, V1 and W1. Voltage levels must be 3-Phase 360 to 455 VAC or
480 VAC (+6%/-10%). Check line voltage U1 to Gnd, V1 to Gnd, W1 to Gnd. Voltage must be symmetrical
(Line to Line Volts / 3)
Check voltage across terminals L1 and L2. L1 must be in phase with U1, L2 must be
V1. Terminals L1 and L2 are only present on 80 and 120KW units!
D) POWER DOWN, wait for the DC Bus to discharge(about 5 minutes)
.
CAUTION: Be sure that there
is no voltage across terminals P600 and M600 before proceeding.
E)
Connect the suggested enabling circuit or equivalent for terminals X121.63, X121.64 and X161.48. Do not
enable 63, 64 and 48 at this time! Plug in connectors X121, X161, X171 and X181. Note: X171 has factory
installed jumpers between terminals NS1 and NS2 and X181 has factory installed jumpers between terminals
(1U1-2U1), (1V1-2V1) and (1W1-2W1). If X171 and /or X181 are used in the machine interface, it is
suggested that the factory jumper configuration be used at this time.
F) Power Up.
The green LED should be on, indicating that the Pulse(X121.63) and Drive(X121.64) enable
signals are OFF. Auxiliary voltages should be present at X141 terminals 7(+24V), 45(+15V), 44(-15V) and 10(-
24V) all with reference to terminal 15 indicating that the low voltage power supply is functioning. Enable
supply v24V) should be present at terminal X121..9 with reference to terminal X121.19. The yellow
LED should be off because terminal 48 is not enabled.
G)
CAUTION: There will be approximately 500 to 620 VDC across the DC Bus terminals P600 and
M600.
Enable terminal 48. The Yellow LED should come on, indicating that the internal circuits are OK and
the internal DC Bus contactor has closed. Ready/Fault relay terminals X111.72 and 111.73.1 will remain open
if S1 Bit 2 = OFF(if S1 Bit 2 = ON the relay terminals will close indicating “no fault”). Overtemperature relay
terminals 5.1 and 5.3 will remain closed indicating “no overtemperature” and auxiliary contacts X161.111 and
X161.113 should close indicating that the main internal DC Bus contactor is closed.
H)
Enable terminals 63 and 64. For I/R Modules, the DC Bus Voltage Regulation function will begin. If S1
Bit1 = off and Bit 4 = off, the DC Bus voltage across terminals P600 and M600 will be 600 VDC. If S1 Bit1 =on
and Bit 4 = off, the DC Bus voltage will be 625 VDC. If Bit 4 = on, the DC Bus voltage will be the line to line
voltage *
√
2. For UE Modules, the DC Bus voltage will be the line to line voltage *
√
2. The green LED will go
OFF indicating that the I/R Module is enabled. The Yellow LED should remain on, indicating there are no
internal problems. If S1 Bit 2 = OFF, the Ready/Fault relay terminals X111.72 and X111.73.1 will now close.
I)
If all steps were successful through step H), the I/R Module is functioning properly.
Disable terminals 48,
63 and 64 and then POWER DOWN.
CAUTION!!
WAIT FOR THE DC BUS VOLTAGE BETWEEN
TERMINALS P600 AND M600 TO DISCHARGE TO A SAFE LEVEL BEFORE PROCEEDING.
The
Discharge time can be up to 5 Minutes.
After the DC Bus has safely discharged, the machine interface can
be connected and tested.
