SECTION 6 — COMMISSIONING
When commissioning the Ingersoll Rand 302 Series
VFD, carry out the following procedures before
attempting to start.
It is recommended that an authorized and trained
product supplier carry out commissioning.
Basic operation: The Intellisys monitors the pressure and
attempts to control the pressure by loading and unloading
the compressor. The condition of the unload solenoid is
monitored by the drive and it either runs at a fixed speed
when the compressor is in the unload mode or the drive
runs in a variable speed in the load mode. In the load
mode the speed is controlled by the drive’s set point
compared to the drives pressure transducer.
PHYSICAL CHECKS
Observe correct lockout and safety procedures.
1. Install drive pressure sensor per instructions in
this manual. This should be at the discharge of
the compressor. Remove display from drive and
slide Switches S201 (A53) and S202 (A54) to
the ON position to select current (0-20 mA).
2. Install wiring per diagram that is correct for your
drive size.
RESISTANCE CHECKS
1. Remove the 110VAC fuse from air compressor
control circuit.
2. Measure resistance from RFI side of fuse to all
of the 3TB terminals.
3. Terminals 4 and 5 should be the only ones that
have continuity.
4. Terminal 5 should read approximately 300 ohms
with 3CR plugged in and open with it removed.
5. If the above tests do not pass DO NOT
REPLACE THE CONTROL POWER FUSE
AND APPLY 110 VAC TO THE COMPRESSOR
UNTIL THE WIRING IS CORRECTED. If this
test passes, then proceed to step 6.
6. Remove the relay plug from the drive with
terminals 1-3 and the control plug to the drive
with terminals 12 through 37.
7. Replace the control power fuse, apply power
and repeat test from output of fuse to 3TB (with
plugs still removed).
8. Measure the voltage to 3TB terminals 1 to 5.
9. With 1CR, 2CR and 3CR plugged in and the air
compressor running, loaded or unloaded, there
should not be 110 VAC on any terminal except
terminal 4 to ground (neutral). If this test fails, do
not replace the plugs into the drive until the
wiring is corrected.
10. When wiring is correct, then remove power and
replace the relay and control plugs in the drive
and proceed to the Power-Up Checks.
KEYPAD OPERATIONS
The "Main Menu" button starts programming.
The "OK" button selects either the parameter to change
of accepts the entered value.
The "UP" and "Down" buttons either scroll up and down
the menu selection list or the available values list.
The "Back" button backs out of the menu selection one
step at a time.
The "Status" button will return to the starting screen,
hitting "Menu" again will return you back to where you left
the programming.
The numbers in upper right hand corner show the active
setup that is being edited and the setup that is being
selected by the input is in ().
POWER-UP CHECKS
1. With Power OFF, Pull relays 1CR, 2CR and
3CR relays from their sockets.
2. Power up unit.
3. Set drive to factory default first by changing 14-
22 to 2 and then cycle power.
4. After Power up the Ingersoll Rand 302 Series
VFD should now be in Setup 1. If not, then
change to Setup 1 using parameter 0-11
5. Enter the parameters for Setup 1
a. Only non factory default values are
listed
6. After entering parameters for Setup 1, copy
Setup 1 to Setup 2 using parameter 0-51
7. Link Setup 2 to Setup 1 using parameter 0-12.
8. Now change the active setup using 0-11 and
enter the parameters that are different in Setup
2. (3-02, 3-10, 3-41, and 3-42)
9. Link Setup 2 to Setup 1 using parameter 0-12.
10. Power down unit and replace relays removed.
11. Jog drive to determine correct phasing of
motors. Shut off power and correct rotation.
12. Perform Intellisys setup.
