HOKKIM INTEGRATED AMF CONTROL BOARD MANUAL FOR MODELS:
HAMF-8 AND HAMF-4
INTRODUCTION
Thank you for purchasing the Hokkim Integrated Automatic Mains Failure Control Board model HAMF-
8 or HAMF-4. We shall strive to provide you with the best service in terms of technical support, stock
and parts replacement. This manual should be read through before attempting to install the unit or replace
faulty parts. A copy should be handed to the owner's maintenance team for future reference.
The design and development of the Hokkim Integrated AMF models comes from many years of studying
the traditional AMF boards hard wired with relays and timers. The integrated AMF is based on traditional
timers and relays and not on micro controllers. It is very flexible, comes with many features and easy to
use. Due to our policy of continuous development, we welcome suggestions for improvements. Thus,
there may be changes after this manual is printed. If in doubt, do not hesitate to call for our technical
support.
PARTS IDENTIFICATION
Figures 1 & 3 show the top faces with labeling of Light Emitting Diode indicating lights and knob
adjustments for the respective model. While figures 2 & 4 show the bottom base Printed Circuit Board
with labeling of terminals and plug-in PCB cards. We will now identify each PCB card and familiarize
you with the LED indicating lights and knob adjustments. Once familiarized, you will be able to follow
the operation of the Integrated AMF and identify problems when they occur and replace the appropriate
card.
