Yaskawa AI-010 User Manual

3-15PSI Pressure Transducer Option Card

Part Number: AI-010.

Applicability: E7, F7, G7, P7, GPD506/P5, E7L (Electronic Bypass Control). Introduction: This pressure transducer option card converts the air pressure (3-15PSI) applied to its on-board sensor to

electrical current, usable by both industrial and commercial air-conditioning systems. It can be used both as reference or feedback signal generator. In case of feedback signal usage, the signal should be of course inverted by software or external/system hardware. The card output range (4-20mA) is tunable by software or external/system hardware. The card generally needs no calibration, as the accuracy is embedded inside its design.

WARNING

HAZARDOUS VOLTAGE CAN CAUSE SEVERE INJURY OR DEATH.

LOCK ALL INCOMING POWER SOURCES IN “OFF” POSITION.

CAUTION

• To prevent physical damage to the Drive or E7L Panel, Read these instructions thoroughly b efore installing.

• In GPD506/P5 Drives, an internal operator cable connects the front cover to the Drive. Take care when removing the front

cover.

• After installing the option, ensure all screws are tightened and the front cover is securely in place.

3-15PSI Pressure Transducer Option Card

Pressure Transducer Installation on E7, F7, G7, P7 or GPD506/P5 Drives

1. Turn OFF all power to the drive.

2. Remove the drive’s front cover. Verify that “CHARGE” indicator lamp is off.

3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals (L1, L2, L3).

4. Unpack and verify the contents of the option kit (See Figure 1).

5. Drill a 13/32-inch hole through the enclosure taking care not to damage any internal com ponents. The hole may be drilled in any area that will not restrict or create crimps in the vinyl tubing when installed. Remove any burrs from the drilled hole.

6. Skip to step 7.

Pressure Transducer Installation on E7L Electronic Bypass Contro l

1. Turn OFF all power to the panel.

2. Remove drive front cover, if available. Verify that “CHARGE” indicator lamp is off.

3. Verify voltage has been disconnected by using a voltmeter to check for voltage at incoming power terminals (L1, L2, L3).

4. Replace and secure the drive front cover, if available.

5. Unpack and verify the contents of the option kit. See Figure 1.

6. Drill a 13/32-inch hole through the enclosure taking care not to damage any internal com ponents. The hole may be drilled in any area that will not restrict or create crimps in the vinyl tubing when installed. Remove any burrs from the drilled hole.

Refer to Figure 2 – Installing Adapters (All)

7. Thread the hose barb adapter into the inner adapter and tighten securely. Then insert the assembled hose barb and adapter, with flat washer, through the drilled hole from inside the Drive enclosure, thread the second adapter on from the outside and tighten securely.

8. Press one end of the vinyl tubing onto the hose barb of the transducer on the Pressure Sensor Card.

Refer to Figure 3 – Installing Pressure Sensor PCB on E7, F7, G7, P7 or GPD506/P5 Drive

9. Install the Pressure Sensor Card on the drive’s control board terminals as shown in Figur es 3 and 4. The fingers will fit inside the terminal holes of the Drive, (Terminals FI, FS, and FC for GPD506/P5 drives or A2, +V and AC for E7/F7/G7/P7 drives). Please note that the card will be mounted with topside up, where the components are visible and not the soldering. The (2) terminals “+V” and “AC” on the card are connected to the same (2) fingers on the card, and are provided for customer thru connections (They are not used by the card).

10. Route the tubing the best way to the barb fitting, cut off any excess length and press onto the barb. If the tubing is already pressed onto the barb, use a knife to place a sideways slit into the tubing, at the barb to remove it. Then cut the tubing to desired length and press onto barb.

11. Connect the 3-15PSI pneumatic signal to the adapter on the outside of the drive enclosure.

12. Apply the maximum pressure (20PSI) to the hose to verify its proper installation and detect any leakage or breakage. After this test, lower the pressure down to minimum (less than 2PSI) or zero.

13. Skip to step 14.

Refer to Figure 4 – Installing Pressure Sensor PCB on E7L Electronic Bypass

9. If option J or L (Lonworks) is installed, a wire-jumper should be placed between pins 2 and 7 of TB5. For this purpose, you

might need a short or right-angled screwdriver.

10. Again if option J or L is installed, set S4/2 to ON position, otherwise set it to OFF.

11. Install the Pressure Sensor Card on the Electronic Bypass Control inside the E7L Bypass panel, as sho wn in F igure 4.

The fingers will fit inside the terminal holes of the board’s TB5, Pins 7, 8 and 9. If the transducer card is to be installed on the Electronic Bypass Control, in the field, a short or right-angled screwdriver will be necessary to tighten the three terminal screws. Please note that the card will be mounted with topside up, where the components are visible and not the
