Section CONTROLS Page 514 <br /> Dated JUNE 2008 <br /> L. The controller shall have inputs for five normally open float switches;they shall be Low Level,Pumps Off,Lead Pump <br /> On, Lag Pump On, and High Level. The float inputs shall be not more than 5VDC when open, and not more than <br /> 26mA when closed.The controller shall have LED indication of float status and a float simulation push-button for each <br /> float. The low float simulate button shall simulate the float opening; all other float simulate buttons shall simulate the <br /> float closing. <br /> M. The controller shall perform a series of tests during operation to ensure that the system is operating properly. These <br /> tests include: <br /> Float Sequence: The controller shall detect if floats are activated/deactivated in the correct sequence <br /> (LOW-OFF-LEAD-LAG-HIGH).Should one of the floats activ: - deactivate in the incorrect sequence,the floats out <br /> of sequence LED shall be activated. <br /> Fail To Start(optional):When a pump is called for,the controller starts an internal clock.If the start acknowledge input <br /> isn't activated before the timer times out,the pump that failed to start shall be disabled,the pump disabled LED shall be <br /> activated,the lag pump shall be called,and the condition shall require manual reset. <br /> Over Temperature: The controller shall have inputs for pump motor heat sensors. If this input senses an <br /> over-temperature condition,the temperature fail LED and output are both activated;this shall also disable the pump. <br /> Seal Fail(moisture):The controller shall have inputs for pump seal fail(moisture)sensors.If the input senses less than <br /> 50,000 ohms across the seal probes,the seal fail LED and output are activated and the pump is demoted to lag pump; <br /> this will not disable the pump. <br /> Options for Over Temperature&Seal Fail:If necessary,the controller can be set to latch the motor over temperature <br /> alarm condition,so that the reset button must be activated in order to reset the alarm condition.In addition,the seal fail <br /> (moisture)input can be set to detect a resistance of greater than 50,000 Ohms instead of less than 50,000 ohms. <br /> N. The controller shall have a 3-position switch that chooses among Pump 1 run as lead,Pump 2 run as lead,and automatic <br /> alternation of the lead pump. <br /> 0. The controller shall have 5 relay outputs rated for 7 amps max. at 120VAC.They shall be four SPST contacts (Pump 1, <br /> Pump 2, High Level, Horn/Aux) and one SPDT contact (Low Level). The controller shall have LED indication of the <br /> status of each of the relay outputs. <br /> P. The controller shall feature delays for each pump turning on and off,preventing both pumps from turning on and off at <br /> the same time,and also preventing a water hammer effect.There shall be an option to set this delay to either 6 seconds <br /> or 12 seconds. <br /> Q. The controller shall have seven open drain FET fault outputs that will drive a maximum of 40mA when activated.The load <br /> shall be powered by 12VDC supplied by the controller, and the outputs shall have built-in diode protection to allow <br /> connection of a 12VDC relay.These fault outputs shall indicate Seal Failure,Temperature Failure,and Disabled/Failed to <br /> Start for each pump,as well as Floats Out of Sequence.The controller shall have LED indication of the status of each of <br /> these faults. <br /> 44 <br /> HYDROMATIC' <br /> Pentair Water <br />
