Step 9 RELAY MOUNTING - on PCB

MATERIALS NEEDED:

1 -- PCB - worked on in STEP 4

2 -- OMRON ELECTRONICS - RELAY,G5LE-1 DC5

1 -- 3/64" drill bit

RELAY MOUNTING:
RELAYS need to be mounted on to the PCB.  In order to keep both RELAY PIN-1 (P1) close together you have to reverse RELAY-2 (R2) it controls OUTLET-2 (O2).  When done correctly both PIN-1 (P1) of the RELAYS will be facing each other.

PROBLEM:
RELAYS will not go into the holes on the PCB as configured.

FIX THE PROBLEM:
RELAY-1 (R1) - needs to be positioned as follows:
PIN-1 (P1) - between  I16 / I17 and J16 / J17 holes
PIN-2 (P2) - in hole I14
PIN-3 (P3) - in hole D14
PIN-4 (P4) - in hole D19
PIN-5 (P5) - in hole I19

RELAY-2 (R2) - needs to be positioned as follows:
PIN-1 (P1) - between  P16 / P17 and Q16 / Q17 holes
PIN-2 (P2) - in hole Q19
PIN-3 (P3) - in hole V19
PIN-4 (P4) - in hole V14
PIN-5 (P5) - in hole Q14

Using the top side of the PCB make a square marking between holes I16 / I17 & J16 / J17 holes.  Make the same type of mark at P16 / P17 & Q16 / Q17 holes.

In the center of the square marking formed by the holes drill a 3/64" hole in each square marking.

PIN-1 (P1) on each RELAY will now have a hole to rest in.

PROBLEM FIXED:
You can now insert the RELAYS in to the correct holes and the RELAYS will sit flat on the PCB.

RELAY-1 (R1) MOUNTED:
insert RELAY-1 (R1) into the following holes
PIN-1 (P1) - between  I16 / I17 and J16 / J17 holes
PIN-2 (P2) - in hole I14
PIN-3 (P3) - in hole D14
PIN-4 (P4) - in hole D19
PIN-5 (P5) - in hole I19

RELAY-2 (R2) MOUNTED:
PIN-1 (P1) - between  P16 / P17 and Q16 / Q17 holes
PIN-2 (P2) - in hole Q19
PIN-3 (P3) - in hole V19
PIN-4 (P4) - in hole V14
PIN-5 (P5) - in hole Q14

RELAY-2 (R2) will be reversed from REALY-1 (R1) and PIN-1 (P1) of each RELAY will face each other.

KNOW YOUR RELAY PINS:
Now that the RELAYS are in place you need to know PIN locations on the back side of the PCB.
