General Maintenance
Changing the Fuse
Important Notes
• The fuse protects the internal electronic circuitry. If the display lights up when power is turned on,
you DO NOT need to replace the fuse.
• This procedure should only be performed in a “shop” environment, n ever a “field” environment.
• The most probable cause of fuse failure is a defective or inappropriately sized generator. If you
have a fuse problem, check your generator first.
Tools Required
• 1/8” Flat Blade Screwdriver
• 5 X 20mm, 250V, 2 Amp Slow Blow Fuse
Use a Cooper Bussmann Fuse (Part# BK1/S506-2-R) or equivalent.
Procedure
1. Insert a screwdriver into the slot in the fuse holder cap. Press in slightly, while turning counter-
clockwise, then remove the cap. The fuse should come out when the cap is removed.
2. Remove the old fuse and replace it with the new one.
3. Replace the fuse cap by pushing down and turning it clockwise.
Power Sources
When installing electrofusion fittings in field applications, it is necessary to have a reliable source of AC power
for the processor. This AC power source should:
• be well maintained and subjected to a periodic maintenance schedule.
• provide output voltage within the specified operating range.
• contain a matching outlet, which is required to connect with the plug equipped on the processor:
o
120V models — 30 Amp, 125 Volt, NEMA L5, twist-lock
Utility Power
Utility power is a reliable and ideal power source for the processor. However, it is not always practical to gain
access this kind of power source in field applications. When fusing with utility power, a dedicated connection
to the service panel is recommended because the potential amperage draw is very high.
Generators
Fuel powered generators are also a good power source of electrical power for the processor. Always make
note of the minimum fitting power requirements. Additional power capacity is recommended for intangibles
(i.e. powering other accessories, wear and tear, etc.). Before starting a fusion, it is important to make sure:
• the generator has enough fuel to complete the electrofusion cycle.
• the auto-throttle is disengaged (in anticipation of immediate power draw).
