2. INSTALLATION Fig. 1, Typical Installation Diagram A. LOCATION: The ABC Series Controllers are designed for ease of installation. Select a mounting location convenient to electrical and plumbing connections and easily accessible by the operator for cleaning and maintenance. The enclosure is corrosion resistant and will stand up to most industrial envi- ronments. - Page 5 (Refer to Fig. 2, Controller Dimensions). C. ACCESSORIES: (Available through your Pulsafeeder distributor or sales representative, but not included as standard) Boiler Conductivity Timed Sample: 1. Blowdown valve, solenoid and strainer or motor oper- ated ball valve.
- Page 6 JP4 and JP5 are relay driven AC outputs, they change simultaneous- ly and have a maximum output of 5 amps. The ABC 50 has two fuses for protection, a 1 amp fuse for the controller power supply, and a 5 amp fuse for the relay output. Part numbers can be found in the Trouble Shooting section.
- Page 7 NOTE: Do not connect the ground wire to the Shield (SHD) input. It is for the shield of the probe cable only. NOTE: The ABC 50 does not support temperature compensation. A tempera- ture compensated probe may be used, but will yield non-temperature com-...

Use the test switch to force a system blow down if necessary for gathering a sample of system water. NOTE: For best results, calibrate the ABC 50 at a conductivity as near to the trip point as possible. - Page 9 Fig. 7 Position Trip Point Knob Fig. 8 Turn Cal Adjust Knob 3) Set the trip point knob to the conductivity measured by the hand held meter (Fig. 7). 4) Turn the cal knob fully counter clockwise and momentarily activate the test switch (Fig.

Without some method to compensate for these changes, a unit will consist of the conductivity caused by the particular level of dissolved solids, plus or minus the effect of temperature. The ABC 50 Controller is not compensated for temperature. The user is responsible for maintaining consistent probe tempera-... -
