I just bought a new 2-speed motor (A.O.Smith Century SP1610Z2MC) to replace my old single speed motor. I also bought a Intermatic P1353ME timer to replace the current manual on/off switch. I already had a Goldline Controls Aqua-Rite Chlorine Generator that is wired to receive power whenever the pump switch is on. My power is 240v. I have no other things like a booster pump, heater, spa, etc. I have a few questions about how to properly connect the motor, timer and chlorine generator together.
1. The motor has three terminals labeled "1", "2", and "3 or 4". The label plate show line 1 connected to terminal 1, then for high speed line 2 to terminal 2, and for low speed line 2 to terminal 3/4. Separate from diagram of the 3 terminals, it shows a green to GRD. I haven't disconnected my old motor yet because I'm currently running it to get the pool cleaned up, but at the other end of the conduit coming from the motor is one green wire connected to the switch ground connection and two black wires connected to the load side of the switch. There is also an external bare copper wire connected to a grounding lug on the outside of the motor, that I believe is part of the pool bonding, or is this the "green to ground" shown on the motor plate? (This bare copper wire is connected to the chlorine generator housing.) So how do I connect the 3 wires inside the conduit to both the motor and the timer? Should the green connect to the motor 1 terminal and the two black to motor 2 and 3/4? Then at the timer, the black from motor 2 goes to timer 4 (high speed) and the black from motor 3/4 goes to timer 6 (low speed), but where do I connect the green coming from the motor?
2. People weren't kidding about the poor instructions for wiring the P1353ME timer in reviews I read. It has 8 terminals, 1 & 2 are for "Timer Power", the other three pairs are for line and load for the 3 controlled circuits. So, my incoming power has three leads, but there are only 2 terminals for "timer power". Where do I connect the third power line lead?
3. I will be using Mode 2 of the timer, so circuit #1 will be high speed, circuit #2 will be low speed, and circuit #3 is for an aux that I don't have a need for, unless the chlorinator could be connected there. Do I need to jumper from one of the "timer power" leads (1 or 2?) to the other circuit line terminals (3, 5, and 7)? The timer instructions are silent on this, and the schematics are confusing.
4. Right now, the chlorinator power is connected to the load side of the manual on/off switch. I want the chlorinator to work with either high or low pump speed. The power line from the switch to the chlorinator has three leads, one of which is bare copper. Where should those be connected if I wanted to run it off timer circuit 3? Alternately, could it just be connected to the incoming power supply so that it is powered at all times? It has it's own off switch, and only generates chlorine when it senses flow anyway. (Maybe this is a bad idea in case the flow switch fails closed?) Aside from using circuit #3 or keeping it always powered, is there a way to connect the chlorinator so that it has power whenever EITHER high or low speed is running? That would avoid the need to separately program timer #3 and coordinate it with the high and low speed schedules. This would be my preferred option...where would the 3 chlorinator leads connect in the timer for this?
I'm sure many people have made the exact connections I'm trying to do, so maybe there's already a clear schematic out there that would help me? I need to have the wiring all figured out before disconnecting the old motor to minimize down time while trying to clean up the pool. Bad timing I know...I should have done this over the winter.
Thanks in advance for any answers to the above!
