5-1. General
The battery table components operate on 24VDC.
The internal charging system also incorporates the
components to transform the 120VAC input to
24VDC output to the components.
5-2. Troubleshooting Notes
The basic operation of each component will be
defined along with a figure and an explanation on
how to check it out.
Certain defective components could cause the
entire table to stop functioning or only one control
function to stop. It would depend on what part of the
component failed. Other defective components
would only cause one control function to stop.
The following defective components could cause
all control functions to be affected:
a. Motor/Pump Assembly
b. Main Switch Circuit and Wiring
c. Pendant control
The following defective components could cause
all control functions to be affected or only one
control function:
a. Relay Box
b. Pendant Control
c. Auxiliary Switches
The component listed below would only affect one
control function:
Solenoid
When troubleshooting an electrical circuit, start at
the problem and work back to the power source.
NOTE
•Battery table troubleshooting should be-
gin by switching the operating mode. For
example; if a function fails in the AC120V
mode, switch to the BATTERY mode. If
the function now operates, the problem is
probably located between the power cord
and the relay box. If the function also fails
in battery operation, use the auxiliary
switches. If the function now operates,
the problem is probably in the pendant
control, connectors or wiring from the
pendant control to the relay box.
•All connector pins are numbered usually
with very small numbers.
5-3. Main Switch
The main power supply, 120 VAC, 60 HZ, comes
in through the power cord and through the
Power Switch. The Power Switch opens both
lines when in the "OFF" position. The Power
Switch is also a 10 Amp circuit breaker that is used
to protect the complete electrical system.
a. Main Switch Test
The following test will determine if line voltage is
applied to connector HN1, which in turn would
supply 120VAC power to the table.
1. Plug the power cord into the 120VAC supply
(wall receptacle) and turn the main switch ON.
2. Disconnect connector HN1. See figure 5-1.
Leave all other connectors connected.
CAUTION
Line voltage (120 VAC) will be mea-
sured in this test. Do not touch uninsu-
lated connector pins or meter test leads.
3. Use an AC voltmeter capable of measuring
120 VAC and measure the voltage between pins 1
and 2 (black and white wires) located in connector
HN1. See figure 5-1. You should receive line
voltage 120 VAC.
