HOKKIM HAMF-8 User manual

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
1) ESR - Emergency Stop Relay
RUN (green) LED On - Relay energized to power the rest of the relay cards
STOP (red) LED On - Relay de-energized to cut power to the rest of the cards except the
Energized Stop Timer
2) FMR - Fault Monitor Relay
RUN (green) LED On - No faults detected by the Fault Alarm Relays
TRIP (red) LED On - One or more faults detected Generator Stopped
3) EST - Energized Stop Timer
ON (green) LED On - Energized stop relay and the delay timer activated
UP (amber) LED On - Time delay up and stop relay released
Time Adjustment - 0 to 20 Sec
4) MFT - Mains Fail Timer
ON (green) LED On - Mails failure detected and delay timer activated
UP (amber) LED On - Timer relay energized and start generator sequence activated
Time Adjustment - 0 to 10 Sec
Selection - Normally Open or Normally Close to run
5) SDT - Shut Down Timer & Fuel Solenoid
ON (green) LED On - Fuel solenoid relay activated
ON (green) LED On - Shut Down Timer activated and timer count down begins

TERMINALS IDENTIFICATION
Now we will look at Figure 5 to identify the connection terminals located on the base PCB These
terminal connections shows you how to wired up the Integrated AMF to external relays, push buttons,
selector switch, bell, fault signal input, etc to complete the control board
For easier identification, the terminals are broken into 5 sections, they are; T01 to T32, L1 to L8, S1 to
S8, 11 to 44 and lastly, C1 to C8 A detailed description is given below:
