April 12 –[ trip to JB]-

Monday, after came back from lunch, supervisor suddenly ask me go back pack some clothes follow him to johor.

So both of us start depart from BM at 4.07pm and reached KL, taman connought met with kl branch tester to take ours dinner before continue to JB.
That night we check in at vistania hotel when reached JB, we thought that it would just take us 2 days to complete the repairing however we are wrong.On Tuesday morning, supervisor tried to find out what’s wrong with the lift. It’s so obvious that the sub contractor from penang that set up the elevator did not work properly. The alignment of the cart was run about 5degree which cause the lift can’t run on track smoothly. Moreover, the glasses got crack because the previous sub contractor force the glasses into the cart but we know that the sizes do not suit the cart. As consequences, we have to carry on the blame from the owner which was not our fault.
So we decide to discuss with sub contractor from JB for the repairing the lift. Since these day we could not do anything, without wasting time we depart to Spg Renggam for check up on next lift.
On Wednesday, at the time we reached there, the owner was so busy with clearing the top of the house since the previous night rained so heavy. Our elevator was affected also because the water flowed into the gap between lift doors. The top of the cart flooded with rain water cause the controller board and door operator board damaged. So these day again we focused on alignment only while waiting for order new parts to reach for replacement.

So on Thursday, after obtained the parts, replaced the components, and place a new glass for the lift. So new problem occur where we could not set the speed for open and closing the lift door. We took more than 12hours just on the inverter.This is how the inverter looks like. it's control the speed of energy needed to open the door, brake the door and use a constant speed to lock the door prevent people from forcefully open with hand.Final try before depart to melaka,this time sub contrator do all the check up instead of me . So im free to take pictures of them this time.
Friday, after do a final check up, we have to depart to Malaka to repair next elevator. For this lift, it is more easy just need to order new coil for the door switch and replace them. Total 2 part damaged. It’s already, so we have to stay one night with kl tester. So I take this chance to go back to my apartment visit my housemate.

Saturday morning, I followed other tester to fix one lift at perking duck restaurant. And next destination is Bangsar where the owner want change a new hydraulic pump. After settle everything only depart back to Penang. So this week took all my turn to learn how to check and repair what is need to repair.

9th april 2010 –[Minor injure during work]-

Today supervisor showed me a piece of site map, and teach me how to calculate the length of cable needed to link from power box to the elevator base on the given site map.

This is how the cable look like and known as “hoistway”.

Doing half way, I have been order by other department to help him in carry the elevator cast. Forgot to take picture of the cast but have to say that it’s heavy enough to injure your hand if not careful. This is an example if your hand clipped between the cast. Haha

After finished, more forward to start a new stuff which is screwed the ribbon to the push button switch ”it’s switch that used by tester when work in the elevator” and link to female connecter start from pin 4 to pin 13 from brown to black.Due to my home internet connection has cancel, so i post either at friend or gf house. for this post i sent at her hostel at the same time she attached her pretty picture here... ^^"

8th april 2010 –[Story on Multimeter]-


Ribbon with Socket


Male type socket
Today, after complete construct 1 more controller, get to learned new simple stuff but to complete it need long period. This is male type socket(each unit cost RM4), what I need to do is to plug the ribbon to the specific point on socket. After that, check with multimeter whether that socket is in close circuit.
So that time I was searching for multimeter but I called it as ohm meter because I need to set the meter to ohm unit only can check the socket. My supervisor correct my mistake because thought that I was wrong with the term of word I used.
But for me, if I want to measure voltage, I will call it as voltmeter, to measure resistance then named it as ohm meter although the meter still the same item which is multimeter.

After explained to him, he showed me how the actual ohm meter looks like. It’s a DIY meter where he use a speaker, bactery and crocodile clips to create the so called “ohm meter.” haha

5th april 2010 –[First day Internship]-

Saturday came back from kl, without having enough rest morning start my outdoor studies at my home town. What I mentioned here is internship at Niche Elevator Sdn Bhd. That morning after took my uniform from office started with labeling the components on elevator controller which help to guide to plug the cables when construct the board. Afternoon came back from lunch, learned a further step which is wiring. Do wiring for ground and neutral cables for power supply.

Next day on Tuesday, my supervisor gave a piece of paper, where the sketched paper guide us to do wiring on the components. One wrong step can lead to failure or damage on the components.

From here I started to know roughly about the use of relays, psr- phase sequence relay, mcb- mature circuit breaker and why have to separate the power supply to the controller and to the psr units.
