HOKKIM DIGITAL AUTOMATIC MAINS FAILURE CONTROLLER MANUAL FOR MODEL 
DAMF-5.

INTRODUCTION

Thank you for purchasing the Hokkim Digital Automatic Mains Failure Controller model; DAMF-

5.  We will do our utmost  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 in order to 
avoid damage due to wrong connections. You need to be familiar with this manual in order to fully 
understand the functions and features the DAMF-5 can provide for you. A copy should be handed to the 
owner’s maintenance team for future reference with a briefing on how to operate it.

The design and development of the Hokkim Digital DAMF-5 Controller comes from many years 

of studying the traditional 

AMF

 boards hard wired with relays and timers. The heart of the DAMF-5  is 

Micro Controller based. It is very flexible, compact, easy to use and comes with many features to suit 
most  

AMF

  needs.   Due   to   our   policy   of   continuous   development,   we   welcome   suggestions   for 

improvements. Thus, there may be changes after this manual is produced. If in doubt, do not hesitate to 
call for our technical support or information on our latest models.

PARTS IDENTIFICATION

We are briefly going through the physical markings of the DAMF-5 so that you can easily locate them 
when needed.

1. Front Face Diagram 1.

 

  Refer to page 4. It shows the front face of the DAMF-5. There are 6 nos. red 

LED to indicate; 1) STARTER. 2) RUN. 3) FUEL SOLENOID. 4) ENERGIZED STOP. 5) 24V. 
and 6) 12V. During operation, these LEDs give a quick indications of what the DAMF-5 is doing.
Next is the 3 digit 7-segment display. This display is the most important interface as you will 
receive a host of information from it. To help you understand, we have provided the 3 digit 
abbreviations   at   the   front   face   for   easy  reference.   You   need   to   familiarize   yourself   with   the 
abbreviations as during operation, the display flashes at half second rate, you have to be quick to 
catch what function the DAMF-5 is performing.

2) Terminal Diagram 2

 

 . Refer to page 5. It shows the back terminals from T01 to T24 with the terminal 

abbreviations. Note that some of the abbreviations are the same beside different terminal number. 
This is the part where you have to be careful during connection. The top row of terminals T01 to 
T08 has a mixture of inputs, outputs, and auxiliary supply inputs. Beside T08 is marked 12V or 
24V,   you   can   connect   an   auxiliary   supply   of   12VDC   or   24VDC   and   the   DAMF-5   will 
automatically   switches   to   the   correct   voltage.   The   front   face   LED   voltage   indicator   should 
correspond with the auxiliary supply connected. The middle row of terminals T09 to T16 is clearly 
marked INPUTS. This is where you terminate the inputs from selector switches or alarm contacts. 
The   bottom   row   of   terminals   T17   to   T24   is   clearly  marked   OUTPUTS.   This   is   where   you 
terminate the outputs to relays or lamps. Lastly, at the bottom right is a tiny button marked SET. 
This button allows you to change default settings of the DAMF-5.

3) Terminal Abbreviations Diagram 3.

 

  Refer to page 7. On one side of the DAMF-5 is the Abbreviations 

For   Terminals   sticker.   It   shows   what   you   are   suppose   to   connect   to   each   terminal.   After 
familiarizing yourself with it, it speeds up connection work as you don't need to keep referring to 
the Connection Diagram 5.
