AT THE POINT OF STARTING A CABLE INSTALLATION THE HYDRAULIC PRESSURE WILL BE
BETWEEN 290
-
435 PSI (20
-
30 BAR). IF HIGHER VALUES ARE REACHED
DO NOT CONTINUE
, SEE
SECTION
‘
RUNS AT HIGHER THAN EXPECTED PRESSURE
’
TO RECTIFY PROBLEM BEFORE
COMMENCING CABLE INSTALLATION.
WILL NOT ACHIEVE MAX PRESSURE
•
ON/OFF control valve not open fully
•
Faulty power pack (check performance output)
See Jetstream Pressure Test on page 25
•
Cable clamping force not correctly set (Allowing belt slip)
•
Worn belts due to cable slip
•
Excessive lubrication blowback (on to belts causing belt slip)
RUNS AT HIGHER THEN EXPECTED PRESSURE
•
Excessive clamping force on cable.
•
Seized bearings
•
Over tightening of belt tensioning screws
•
Cable drum not rotating freely on shaft
•
Poor duct and installation causing high cable frictions
•
Insufficient out
-
put from compressor (See recommendations for duct diameter on page 8)
•
Incorrect seal/collet fitted
•
Dirt/debris in belt drive
PROVISIONAL BELT ROTATION TEST
:
-
With Hydraulic power pack running and without cable, revolve the
Drive Belts and monitor the minimum hydraulic pressure required. This should be around 220
-
360 psi (15
-
25) Bar as a benchmark.
CABLE BLOWING MACHINE STOPS SUDDENLY DURING CABLE INSTALLATION
•
Maximum Hydraulic pressure achieved
•
Obstacle in duct installation
•
Power Pack out of fuel
•
Emergency button pressed
•
Damaged lead between Power Pack and blowing machine
ENGINE DOES NOT STOP AT MAX PRESSURE
•
Emergency lead not connected
•
Electrical display not switched on
•
Batteries low on power
•
Fuse blown in control panel
•
Incorrect pressure switch setting
EXCESSIVE AIR LEAKAGE FROM AIR CHAMBER
•
Damaged cord seal
•
