Armstrong World Industries ACUM110 Instruments Reading, Engine Checks During Operation, Fuel

7.4. INSTRUMENTS READING

Additional to the digital module, the control panel has ana- log capabilities hat provide more durability and low mainte- nance cost.

Those instruments are:

•Amperes meter

•Volt meter

•Frequency meter

•Temperature meter

•Oil pressure level

•Battery charge meter.

To check the readings of volts, amperes ad frequency of each phase the control panel has a toggle switch that will allow to change between the readings of each phase.

tion number 2, will give the readings of the phase L2, and position number 3 will give the reading of the phase L3 only on 3 phase equipments. Single phase equipments will give no reading on this position.

8.1. CHECKS DURING OPERATION

While running, make the following checks to see that all parts are working correctly.

Radiator Cooling water (Coolant)

To avoid personal injury:

•Do not remove radiator cap until coolant temperature

is well below its boiling point. Then loosen cap slightly to the stop position, to relieve any pressure, before removing cap completely.

When the engine overheats and hot coolant overflows through the overflow pipe and cannot be stopped, stop the engine immediately and make the following checks to deter- mine the cause of trouble:

1.Check to see if there is any coolant leak;

2.Check to see if there is any obstacle around the cooling air inlet or outlet;

3.Check to see if there is any dirt or dust between radiator fins and tube;

4.Check to see if the fan belt is too loose;

5.Check to see if radiator water pipe is clogged; and

6.Check to see if anti-freeze is mixed into coolant in warm seasons.

Fuel

To avoid personal injury:

•Fluid escaping from pinholes may be invisible. Do not use hands to search for suspected leaks; Use a piece of card- board or wood, instead, If injured by escaping fluid, see a medical doctor at once. This fluid can produce gangrene or a severe allergic reaction.

•Check any leaks from fuel pipes or fuel injection pipes. Use eye protection when checking for leaks. Be careful not to empty the fuel tank. Otherwise air may enter the fuel system, requiring fuel system bleeding.

While the engine is run within the rated output range:

•The color of exhaust remains colorless.

•If the output slightly exceeds the rated level, exhaust may become a little colored with the output level kept constant.

•If the engine is run continuously with dark exhaust emis- sion, it may lead to trouble with the engine.

•Immediately stop the engine if;

•The engine suddenly slow down or accelerates.

•Unusual noises suddenly appear.

•Exhaust fumes suddenly become very dark.

When it is on he of position no lecture will be received. Posi- tion number 1 will give the readings of the phase L1, posi-

8.2. MAINTENANCE SCHEDULE

Perform maintenance at whichever interval that occurs first. At each scheduled maintenance interval, perform all previ- ous maintenance checks that are due for scheduled main-
