  25 transmitter  or  receiver  will  generate  a  simple  and  clear  alarm.  Not  only  the operator  and  maintenance  personnel  can  fully  understand  the  condition  of remote controller,  but  can also  reduce  the  maintenance  time  by  following  the error message for repair.     Note: 1. Malfunction alarm mode can be set by dip switch “SW8” in the “Receiver/ Decoder”  module  for  the  Simple  Alarm  Mode  or  Morse  Alarm  Mode. Simple Alarm Mode was discussed in Operator’s Manual. The  following explains the “Morse mode” for the error message. 2. Alarm (error message) is shown according to Morse code. “” Indicates short alarm for a duration of 0.26 second; “” indicates long alarm for a duration  of  0.78  second;  interval  between  alarms  is  0.26  second.  An example for transmitter pushbutton error message is shown as follows:                    “” 0.26 sec 0.26 sec 0.78 sec    1.5 sec 3. When  an  error  message  is  detected  by  receiver  or  transmitter’s  self-diagnostics, an alarm will sound and “Power-OFF’ will be activate. Unless the malfunction has been corrected, it will be impossible to Power-On the controller. 4. Technicians  for  maintenance  can  use  error  message.  However,  we recommend the technician replace only the module. The defective module should  be  returned  to  our  distributor  for  the  repair  of  components.  This will eliminate further damage to the controller. 5. If you do not understand the error message from the transmitter or receiver, or the signal is not listed in this manual, please contact our distributor for clarification and recommendation.       4-1-1 Transmitter’s Malfunction and Correction  Error Message Item Morse Code  Description  Correction 1  C •• Malfunction  of  E2PROM memory  in  the  encoder module; can’t read /write. 1.

When receiver’s self-diagnostics detects a malfunction, alarm will continue, unless the  malfunction  has  been  corrected  or  the  power  to  the  receiver  has  been disconnected. 2. The  receiver  can  be  set  by  the  software  to  alarm  or  not,  when  error  occurred relating to item 20 ~ 21.   3. The receiver can be set by software to close the relative action (i.e. “Relay-Off”) or “Power-Off” automatically, when the error occurred relating to items 20 ~ 22. In the other items, the receiver will enter into the Auto Power-Off mode. 4. This receiver contains Auto Gain Control circuit with high sensitivity; when not in operation,  it  may  receive  weak  signal  from  unknown  sources.  As  long  as  the interference does not occur very often, it will not affect the normal operation. No frequency change is necessary.
  29 4 – 2    Malfunction Identification.  When remote  controller  can’t  function  properly (e.  g.  Receiver  can’t function correctly after pressing the pushbutton of the transmitter) and there is no alarm for malfunction information, please follow  the  procedures  below to  check  the malfunctions. Item Malfunction  Action Required 1. Transmitter’s  LED  and buzzer  do  not  react  at all. 1. Make sure battery power is normal: a. Check battery’s direction. b. Check battery box direction. c. Check battery’s condition. 2. Make  sure  micro  control  unit  (MCU)  is normal: a. Press EMS mushroom and turn security key to “OFF” position. b. Remove  battery  cover  and  take  out batteries  ,press  and  release  any  one  of pushbuttons  on  Transmitter,  then  put batteries  into  battery  compartment  and screw  up  the  battery  cover  .  At  this  time, buzzer  should  generate  two-long  sound. Otherwise, the MCU is out of order or  the power connecting wire is abnormal. 3.Return for repair.
  30 2. Transmitter  is  normal but  receiver’s  buzzer doesn’t react at all. 1. Make  sure  the  receiver’s  power  source  is normal: a. Inspect “Receiver/Decoder” to  see  if  the  SQ indicating  light  is  on  and  the  Diversity’s ANT A and ANT B flash alternatively. b. Inspect AC power fuse and DC power fuse to see if the fuse is burnt out. If necessary, turn off the main power and replace the fuse. 2. Make  sure  the  “Receiver/Decoder”  module and “Relay” module are wired correctly. 3. Make sure the output fuse of the relay is not burnt out. Replace fuse if necessary. 4. Make  sure  the  Alarm’s  relay  is  not  out  of order. (If the Alarm’s LED is on, it means the relay is out of order.) 5. Return for repair. 3 Certain motion does not work. 1. Make  sure  the  output  fuse  of  the  relay  is  not burnt out. Replace fuse if necessary. 2. Make sure the original control system of crane works  properly.  If  not,  ask  for  the  original manufacturer to repair. 3. Return for repair.
