• on plastic surfaces

3. To apply the probe, clean the mounting surface with isopropyl alcohol, and allow to dry thoroughly. Remove the protective backing from the doublefaced adhesive tape on the probe, and securely press it onto the surface.

4. Install the cable supplied with the temperature compensation probe kit:

• Start at the AT10.1. The end of the cable with two (2) stripped wires and

a quick-connect terminal will be installed inside the AT10.1.

• Leave 30in / 762mm of cable inside the enclosure, and route the other

end to the probe at the battery.

INSTALLING THE AT10.1

• Run the cable though a conduit if possible, but not through a conduit containing any power wiring.

NOTICE

If the s tandard (25ft / 7.6m) c able is not long enough, longer cable assemblies ar e av ailable in lengths of 50, 100 & 200ft / 15.2, 30. 5 &

61.0m. See Appendix B on page 71 for ordering inf or m ation.

• Make sure all wiring conforms to NEC, local, and site requirements.

5. Attach the interconnection cable to the AT10.1 as shown in the figure below:

• Route the cable within the AT10.1 enclosure so it runs with the wire harness to the back of the front panel, and easily reaches the Main Control PC Board (A1).

• Route the other end to the probe at the battery and coil up excess cable.

• At the Main

Control PC Board (A1), insert one of the bare wires from the cable into each terminal of TB8. Polarity is not vital.

• Plug the connector at the end of the nylon-shielded wire of the cable assembly onto J6.

• Using plastic wire ties, fasten the interconnection cable loosely to the existing wire harness. Make sure that the cable conforms to the service loop at the hinge end of the door.

6. At the battery, connect the quick-connect terminals to the temperature compensation probe. Polarity is not vital. Coil up any excess wire and tape or tie it together to prevent damage.

7. Set jumper (J30) on the Main Control PC Board (A1) to positions 2-3 to use compensated voltages, or to positions 1-2 to use uncompensated voltages.

INSTALLING THE AT10.1

8. Check your work. Confirm that:

• All connections are secure.

• The shield is connected to ground at the charger end only (A1-J6).

• The cable is connected to the 2-position terminal block (TB8) on the

Main Control PC Board (A1). Other terminal blocks may look similar.

9. Restart the AT10.1 using the startup procedure in Section 2.1. During

startup, the AT10.1 displays Pb on the front panel meter, indicating that the temperature compensation is set up for lead-acid battery types. While this is being displayed, you can press any front panel key to change the display to read nicd, to change the temperature compensation setup for nickel- cadmium batteries. The choice you make is saved internally, and will be used again by the AT10.1 the next time it starts.

10. Adjust the output float and equalize voltages to the battery manufacturer's recommended values, using the AT10.1 front panel meter, as described in Section 2.3.2.

If the temperature compensation probe, or the probe wi ri ng, i s damaged and becomes an open circuit, t he AT10.1 detect s the damage and displays E 08 on the front panel meter. The AT10. 1 t hen reverts t o normal non-temperature-compensated operation unt il the probe or wiring is repaired. Once the probe is repaired, you must restart the AT10.1 to act i vate the probe, as described in Section 2. 1.

NOTICE

Using temperature compensation

When an electric storage battery is being charged, the terminal voltage of the battery c ha nges a small amount whenever the ba tter y te mper a tur e changes. As the battery temperature increases, its terminal voltage decreases. When a constant output voltage float type rectifier charges a battery, float current increases when the temperature increases. This results in overcharging the battery, which can result in damage to the materials, or at least the need for more frequent maintenance.

When the AT10.1 is equipped with a temperature c ompe nsa tion probe, it is able to adjust the output voltage applied to the battery to keep the float curre nt c onstant, ther e by a voiding overchar ging. The pr obe se nse s the ambient temperature at the battery, and adjusts the output float/equalize voltages to compensate for variations in temperature. If the ambient temperature increases, the AT10.1 output voltage decreases.

If you are experiencing any inconsistencies in the AT10.1 when the tempera ture c ompensa tion probe is utilized, tempora r ily disc onne c t the probe, a nd r e fer to the Ap plication Note (JD5003-00

) for further details.

INSTALLING THE AT10.1

N ote t he follow ing:

• You should set the Float and Equalize voltages to the values recommended by your battery manufacturer for 77 °F / 25 °C.

• When you enter the Edit Mode to adjust the Float or Equalize voltage (see Section 2.3.2), the front panel meter displays the 77 °F / 25 °C value for the Float or Equalize voltage, even if the battery is warmer or cooler than 77 °F / 25 °C.

• The actual output voltage of the AT10.1 may be different from the value displayed on the front panel meter, if the battery is warmer or cooler than 77 °F / 25 °C.

• Use a digital meter to measure the actual output voltage of the AT10.1. If you know the temperature at the temperature compensation probe, you can use the graph below to determine that the output voltage is correct.

• If the battery temperature goes below 32 °F / 0 °C, there will be no further increase in AT10.1 output voltage. Likewise, if the battery temperature goes above 122 °F / 50 °C, there is no further decrease in output voltage.

OPERATING THE AT10.1

2. OPERATING THE AT10.1 BATTERY CHARGER

2.1. STARTING THE AT10.1

2.1. 1. Underst anding th e st art up sequence

The AT10.1 is set up at the factory to work with most common batteries and loads without further a djustment. When you start the AT10.1 for the first time, the factory settings (float voltage, equalize voltage, etc.) control the opera tion of the charger. Y ou c a n c ha nge the se ttings after you sta r t the AT10.1. The FACTORY SETTINGS are listed in table on pa ge 25.

The AT10.1 startup routine takes a bout 5 sec onds. The microproc e ssor that controls the AT10.1 initializes the charger by reading the settings that are stored internally. The control circuitry then "soft starts" the AT10.1, and the dc output voltage and current increase gradually to the rated value.

2.1. 2. Checking th e instal lation

Confirm that you have followed the installa tion instruc tions care fully. Chec k the a c input supply voltage a nd the ba tter y voltage, and make sur e they ma tc h the infor ma tion on the AT10.1 data nameplate. Verify that the

jumpers on the m ai n transformer ( T1) are correc t for your ac supply vol tage . Open the

front panel door and care fully chec k the battery polarity at the dc output terminals TB1(+/-).

2.1. 3. Starti ng th e AT10.1

When you are sur e tha t all connections to the AT10.1 are pr ope r ly made, follow these ste ps to start up the AT10.1:

• Turn on (close) the dc output circuit breaker (CB2) first.

• The digital meter indicates battery voltage only. If the meter display

does not light, do not proceed. Turn off (open) the dc breaker (CB2).

• Check all connections and the battery polarity again. Also check the battery voltage. It must be above 50% of nominal voltage to turn on the display. If you cannot find the problem, refer to the Troubleshooting Procedure in Section 3.1 on page 44.

If you at t empt to turn on the dc circuit breaker (CB2) w ith the batt ery connected in reverse polarity, t he breaker w ill immediately trip. Do not try to close the dc breaker again, since t hi s may damage the AT10.1. If your AT10.1 is equipped wi t h dc f uses, one or bot h fuses will blow when the battery is reversed. Correct t he battery polarity before proceeding.

Using the Digital Meter

When you first start the AT10.1, the meter display alternates between dc output voltage and dc output current.

Each reading is held for 2 seconds. Indicator lights to the l eft of the display indicate whether the meter is displaying voltage or current.

If you want to “freeze” the meter to display only vol tage, press the METER MODE key on the front panel. To freeze the meter to display only current, press the key again. Press the key twice more to revert to the alternating display.
