    (100-240 VAC) power supply network which supplies buildings used for domestic purposes. Intended Use The Pulse EP2100 is a microprocessor-based measuring and control instrument used to measure water quality parameters and other process variables in a wide range of water and wastewater treatment applications. Operating the instrument in any way other than as described in these instructions may compromise the safety and function of the measuring system and is therefore impermissible.

    Sensor Installation Refer to the specific instructions supplied with the sensor being used, for detailed installation instructions. General Guidelines Locate the sensors where an active sample of water is available and where the sensors can easily be removed for cleaning. Position the sensor such that air bubbles will not be trapped within the sensing area. Position the sensor where sediment or oil will not accumulate within the sensing area.

Install the sensor vertically, with the measuring surface pointing down, at least 5 degrees above horizontal. Flow rate regulation must be done upstream from the sensor, because any flow restriction downstream can increase the pressure above atmospheric and damage the membrane cap! The corrosion sensor should be placed as close to the controller as possible, to a maximum distance of 100 feet...

Depending on your configuration of controller options, you may be required to hard- wire some or all of the input/output devices. Refer to figures 6 through 19 for circuit board layout and wiring. Note: when wiring the optional flow meter contactor input, the 4-20 mA outputs or a remote flow switch, it is advis- able to use stranded, twisted, shielded pair wire between 22-26 AWG.

  • Page 99 When the Lead control mode (R1) determines the output should be activated, R2 turns on because it has the lowest accumulated on-time. After 2 hours, if the output remains activated, the on-times are re evaluated and R2 turns off and R1 turns on because it now has the least accumulated total on time. The cycle continues until the Lead control mode determines the feed is complete.
