PATENTS PENDING

ITEM READING CAUSE

1. Green LED and Red LED ﬂ ash on

for .5 second

Battery power is connected to input of

the relay. To save power, relay enters

sleep mode until power is turned on at

the Lift.

2. Green LED on Power switch was turned on at the Lift.

Relay output is on.

3. Green LED ﬂ ashing fast Voltage is above 16.5 V.

4. Green LED ﬂ ashing slowly Voltage is below 8.0 V.

5. Red LED ﬂ ashing fast Over current.

6. Red LED ﬂ ashing slowly High temperature (over 100° C).

7. Red LED displays 3 short ﬂ ashes Short in FET.

8. Red LED displays 2 short ﬂ ashes Open in FET.

DC RELAY READINGS

NOTE: A fast ﬂ ash is 5 ﬂ ashes per second.

A slow ﬂ ash is 1 ﬂ ash per second.

DC RELAY

The DC Relay (FIG. 88-1) is a

solid-state device for switching DC

load current of up to 100 amps. Un-

like a motor start switch (relay), the

DC Relay uses only a few milliamps

of current and has LED’s to indicate

normal operation or fault conditions

(FIG. 88-1 and TABLE 88-1).

When the power switch on the Lift

is turned on, it checks for power-re-

lated faults before applying power to

the Lift. If a fault is detected, the DC

Relay will not apply power to the Lift,

and the green LED or red LED will

indicate the applicable fault (TABLE

88-1).
