- Page 2 OVERVIEW FOR AMP-HOUR BASED METERS JP Tech’s Ampere-Hour meters incorporate several screen options in the Menu designed for ease of operation, information gathering, and programming. All models incorporate displays showing accumulated Ampere-Hours or Ampere-Minutes (for Amp Hour meters). A resettable Ampere-Hour/Ampere-Minute display is included. In addition, there is a “Shunt”...
- Page 3 MODEL 290-AHP3 MENU OPERATION This model incorporates everything the Model AH-1 (AH Total and AH Total Re-Settable Screens) has plus it can support 2 pumps with associated Presets and Timers or one (1) pump and one (1) rectifier or two (2) rectifiers. All internal output relays are fused. Also, the status of the pump(s) will be indicated in each of the main display screens by either a LmV (Low Millivolt signal = no accumaltion of Amp Hours and the pump(s) is off), P1 (Pump 1 = ON), P2 (Pump 2 = ON), or P12 (both pump 1 and 2 = ON).
- Page 4 MODEL 290-AHP3 MENU OPERATION (Cont.) To the right is the TIMER1 CNT LEFT screen. This screen shows the amount of seconds remaining during the “ON” pump condition. This screen can also be used to add time to the current pump cycle for a one time add without effecting the TIMER1 setting. TIMER2 CNT LEFT for Pump 2 works the same way.
- Page 5 APPENDIX A. CALCULATING THE PRESET AND TIMER VALUES NEEDED: The values you may need to run your metering system correctly can vary significantly. In most cases, the calculations are straightforward and only require a ratio of need chemical additions per amp/hour units. The following is a step-by-step example of how to derive a series of options for an actual situation. The user’s chemical representative should have supplied the feed ratio for chemical per amp/hour.
- Page 6 Keep Seconds and Correct for Error = Ratio: 60.0 amp/hours X [1-0.033(% error)] : 23 Seconds New Ratio: 58.02 Round Up: 59 Difference +0.98 % Error 1.67% Our final setting will be for every 59 amp/hours the pump must run for 23 seconds. Every 18,000 amp/hours (from step 1) you will need to add 63 ml (3784 ml X 0.0167) to correct for the 1.67% error.
- Page 7 INSTALLATION NOTE: WARNING: 110VAC All board components and CHECK circuitry use a “floating SQUEEZE ground” and must remain isolated from all other cir- TUBES PUMP 1 cuits and grounds. This is PUMP 2 REGU- only an issue if board is removed outside its protec- LARLY FOR tive casing.

- Page 9 MAINTENANCE The PERISTALTIC Series of metering pumps require a minimal amount of maintenance to achieve optimal performance. Periodically check the squeeze tube for cracks, deterioration, or swelling. The squeeze tube will typically need to be replaced about every 6 months (chemical compatibility and duty cycle can cause this interval to vary).
