LOAD BANK MANUAL • Merlin 150-300 Load Bank • page 3 of 15

The Local Control Panel is comprised

of the following components:

1. Voltmeter, Ammeter, and

Frequency Meter

2. Control Power, Volt-Ammeter,

Ammeter Range Selector, Control

Power Selector, and Voltage

Selector switches

3. Cooling Failure and Load Over

Voltage lamps

4. Ammeter Range Selector Switch

5. Alarm Reset pushbutton

6. Master Load and load step

switches

The resistive load elements in this

Load Bank are cooled by a horizontal

forced air system. The load system is

connected to the test source via the

load cables.

Part of Typical Local Control Detail Drawing

This Load Bank is equipped with the

following automatic safety systems

which de-energize all load steps when

any condition is present which could

damage the Load Bank or present a

safety hazard to the operator:

1. The Cooling Failure Subsystem de-

energizes any load applied when

cooling of the load elements becomes

inadequate due to fan failure, high

intake air temperature, or high ex-

haust temperature.

2. The Load Power Over Voltage Failure

System removes all load from the test

source in the event the Load voltage

selector switch is in the low voltage

position (less than 240V), and a high

test source voltage (greater than

480V) is applied.
