OverviewThe PLL is a Lead-Lag Pump control. It is designed to operate in different modes to satisfy multiple pumping applications. Tochange the operating mode, set the dip switches. See "Dip Switches" on page 10. It can provide pump lead-lag rotation for two orthree pump systems. With its built-in alarm outputs, the PLL can trigger an alarm whenever a pump fails to provide proof-of-flowwithin 30 seconds. It can also be used to provide pump flow check and run-on delay.The PLL can operate up to 3 pumps. It outputs source 120 VAC power to its pump and solenoid valve outputs. However, alarmoutputs require an external power source.Alarming The PLL is equipped with an alarm output for each of the three available pump outputs. For local indication, it also has an LED for each of the alarm outputs.Alarming on No-Flow If a pump fails to provide proof-of-flow for 30 seconds, by shorting the Flow input terminals, the PLL will turn that pump’s alarmoutput on and blink its alarm LED. If the mode selected offers a rotation option, then the PLL shall turn on the next pump output and its LED.Ending the Alarm If any of the pumps is in alarm, its alarm output will remain on until the Alarm Reset button is pressed. This will cause the Alarmoutput to turn off.Rotation options The PLL offers lead-lag pump rotation in many of its modes. When an operating mode has rotation options, it will havemultiple time-rotation options and an alternating rotation option. You can change the time interval of the time-rotation usingthe appropriate dip switches for the mode selected.

The PLL rotates the pumps based on either timed rotation oralternating demand (per call). The rotation options are selectedvia dip switches. The pump call must be connected to Pump 1 input terminals(C1) (20 and 21). In addition, the flow input must be connectedto Flow 1 input terminals (F1) (26 and 27). Alternating demand activates a different pump each time a pumpcall is initiated. Timed rotation has two options, 1 day, and 7 days rotation. When rotation of the lead pump is to take place during a timedrotation, the operation of both pumps, old lead pump and newlead pump, will overlap for a few seconds to eliminate a no-flowperiod prevent boiler short-cycling. In these modes, if a pump fails to provide proof-of-flow for aperiod of 30 seconds, the PLL will turn it off. Also, it will turnon its alarm and turn on the next lead pump.ALARM 1PUMP 14PLL Installation and Operation Manual
1-Call, 2-Flow (2-Pump) This mode is designed to rotate two system pumps in a hydronicapplication. It is primarily used with Variable Frequency Drive(VFD) pumps. The operation of this mode is similar to the 1-Call/1-FlowMode listed previously. The only exception is that each pumpwill have its own flow input. That means that pump call mustbe connected to Pump 1 call input terminals (C1) (20 and 21).Pump 1 flow input must be connected to Flow 1 input terminals(F1) (26 and 27) and Pump 2 flow input must be connected toFlow 2 input terminals (F2) (28 and 29).ALARM 1PUMP 1PUMP 2ALARM 2PUMP 3ALARM 3VALVE 1COMVALVE 2POWEROUTPUT RATINGS: 2 RESISTIVE, 120VACPLLPUMP LEAD-LAGALARMRESET1/4 HP, 120VAC 60Hz, Pilot Duty 80VA, 120VACMAXIMUM 6A TOTAL FOR ALL CIRCUITSINPUT RATINGS: 120VAC 60Hz, 12VA MAX.CAUTION: Risk of Electric Shock.

It uses an Auxiliary pump / Pump 3 to replace anyfailing boiler feed pump. It does that by turning on a normallyclosed solenoid valve to direct the flow from the failing pump tothe auxiliary pump. No rotation is available in this mode. The PLL control operatesa single pump per boiler. A maximum of two boiler pumps can be connected to a singlePLL. If any of the boiler pumps fail to provide proof-of flow in 30seconds, the PLL will switch its operation to the Auxiliary pump/ Pump 3 (P3). The valve outputs are used to operate solenoid valves to switchthe system flow from the failed pump to the Auxiliary pump /Pump 3 (P3). Valve 1 output (V1) is turned on when Pump 1fails and goes into alarm. Valve 2 output (V2) is turned on whenPump 2 fails and goes into alarm. See "Valve Output Wiring" onpage 9. If a pump fails, the PLL will turn it off and will turn on its Alarmoutput, its Valve output, and the Auxiliary pump / Pump 3 (P3)output. In addition, it will blink its Alarm LED. If the second pump fails for over 30 seconds while the firstpump is in alarm, the PLL will turn off the 2nd pump and turnon its relevant solenoid valve and Alarm LED. In this case, theAuxiliary pump / Pump 3 (P3) replaces both primary pumpsuntil the situation is rectified and the Manual Reset button ispressed.PLL Installation and Operation Manual5
Pump Delay3-Call, 3-Flow (3-Pump) This configuration is typically used in one, two, or three boilerpump applications to offer pump delay and alarming. The PLLcontrol operates a single pump per boiler. Each of the pump calls will use a different pump call input (C1,C2, and C3). Also, each of the pump flows will use the respective pump flowinput (F1, F2, and F3). No rotation is available in this mode. If a pump failed to provide proof-of-flow for over 30 seconds,the PLL will turn that pump output off and turn on its alarm.ALARM 1 dry-contact only.

If the mode selected rotates the lead pump or offers an auxiliary pump operation,the failed pump alarm will cause the lead pump to go the next available pump or theauxiliary pump.AlertHT# 059296-00A The PLL provides 120 VAC 60Hz power to the pump and solenoid valve outputrelays. Each relay can power up to 1/4 HP pump (120 VAC 60 Hz) or 80 VA SolenoidValves (120 VAC 60Hz). The PLL does not provide power to the alarm output relays. A separate power sourcemust supply the power to the alarm.
