LEAD/LAG OPERATION
The Mercoid® MPC pump controller is designed to easily operate a pair of pumps in the most efcient manner possible. The controller has a ‘lead/lag’ feature that allows two pumps to operate in an alternating fashion to minimize wear.
The Mercoid® MPC pump controller has a pair of set points each for pump 1 and pump 2. If the lead/lag feature is turned off, SP1H and SP1L control pump 1 and SP2H and SP2L control pump 2. If the lead/lag feature is turned on, pumps 1 and 2 will be controlled in the alternating fashion described below. In all cases the P1 lamp will indicate activity of pump 1 and the P2 lamp will indicate activity of pump 2. The lead/lag operation is set in the Secure menu with the item LdL9.
Lead/Lag On
After installation, set the SP1H to the high level (pump on point) for standard operation. Set SP1L to the low level (pump off point). Set the SP2H to the level where you want BOTH pumps to turn on (emergency pump on). Set the SP2L to the level where you want the second pump to turn off (emergency pump off).
The controller will not allow you to set SP1H below SP1L,
SP1L above SP1H, SP2H below SP2L, or SP2L above SP2H. The controller will not allow you to set any set point or alarm
point above or below the programmed scale. No error messages are generated. The displayed value will stop at an allowable point just above (or below, as the case may be) the maximum or minimum allowed.
In normal operation, when the SP1H point is reached, one of the pumps will turn on. When lead/lag is turned on, pumps 1 and 2 will alternate. If the level reaches the SP2H point, both pumps will be turned on until the SP2L point is reached, where one of the pumps will turn off. When SP1L is reached, remaining running pump will turn off. The last pump off will not be the next pump on.
Lead/Lag Off
If lead/lag is turned off, SP1H and SP1L control pump 1 and SP2H and SP2L control pump 2. There is no alternating
function.
SEAL FAILURE OPERATION
The Mercoid® MPC Pump Controller is designed to work with most types of submersible pump moisture sensors to detect outer seal failure. Most often the moisture sensor is a conductance device that detects moisture in the oil chamber indicating an outer seal failure. Using a
2.5 VDC power supply sent to the moisture sensor the MPC Pump Controller monitors the resistance between the probe lead wires or the single probe lead wire and ground. The resistance set point is adjustable over the range of 10K to 500K Ω adjustable in 10K ohm steps, and is set with Secondary menu items SFS1 and SFS2. When the resistance of the moisture sensor decreases below the resistance set point the MPC controller goes into the programmed seal failure mode.
7
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
In the Secure menu the value of PSF is programmed for the action of the MPC based on the condition of a seal failure. If set to ˝AUt0˝ when pump moisture sensor indicates that there is a seal failure condition then the corresponding pump seal failure lamp is lit on the controller. The pump will remain in service with only the lamp indication of failure. The lamp will be turned off automatically when the seal failure condition has ceased.
If PSF is set to ˝rES˝ when pump moisture sensor indicates that there is a seal failure condition then the corresponding pump seal failure lamp is lit on the controller. If the MPC is only being used with one pump or being used with two pumps with the lead/lag function turned off then no action is taken by the MPC with the operation of the pumps. The failure indication lamp will be manually reset as described in the next paragraph. If the MPC is being used with two pumps with the lead/lag function turned on then the failed pump will automatically become the lag pump, the remaining pump will become the lead pump, and the alternation will be discontinued. The lamp indication and pump alternation can be manually reset as described in the next paragraph.
Once the pump has been repaired the seal failure action can be reset with the values of P1SF and P2SF in the Secondary menu. The item P1SF or P2SF will display FA1L if the corresponding pump has met the condition of a seal failure. Press the ENTER key to reset. If the pump moisture sensor is still in the fail condition then the control will not reset. If the moisture sensor is no longer in the fail condition then the display will revert to ˝----˝.
OVER TEMPERATURE OPERATION
Most pumps have an installed normally closed thermostat for over temperature protection of the pump. The thermostat has a preset value from the pump manufacturer at which point the pump needs to be shut down. The Mercoid® MPC detects when the thermostat signal changes to open and shuts down the pump.
In the Secure menu the value of P0t is programmed for the action of the MPC based on the condition of the over temperature. When the pump temperature sensor indicates that there is an over temperature condition the pump will be held out of service and the corresponding pump over temperature lamp is lit on the controller. If using the MPC with two pumps with the lead/lag function turned on then the failed pump will automatically be taken out of service, the remaining pump will become the lead pump, and the alternation will be discontinued. When controlling two pumps with the lead/lag function off the failed pump will automatically be taken out of service and the remaining pump will be controlled by the SP1H and
SP1L set points.
If P0t is set to ˝AUt0˝ then the pump will be automatically placed back into service and the lamp turned off when the over temperature condition has ceased. If set to ˝rES ˝ then the pump will remain out of service and the lamp lit until the corresponding manual reset P10t or P20t is reset in the Secondary menu (described in the next paragraph). The pump cannot be brought back into service until the over temperature condition has ceased.
Once the pump has cooled down the MPC Pump Controller can be reset with the values of P10t and P20t in the Secondary menu. The item P10t or P20t will display FA1L if the pump has met the condition of over temperature. Press the ENTER key to reset. If the pump temperature sensor is still in the fail condition then the control will not reset. If the temperature input is no longer in the fail condition then the display will revert to ˝----˝.
ANALOG RETRANSMISSION OPERATION
The analog retransmission allows the Process Variable to be sent as an analog signal to an external device. The signal may be either 2-10 VDC (option RV) or 4-20 mADC (standard). The output may be changed in the eld from one to the other by the toggle switch located on the top printed circuit board, factory standard is mADC.
Wire the output as shown on page 1.
To set up the analog retransmission, rst determine the scale range that the analog signal will represent. The maximum scale is 9999 counts. In the Secure menu set P0L for the scale value that will be represented by the low end of the analog signal (2 V or 4 mA). Set P0H for the scale value that will be represented by the high end of the analog signal (10 V or 20 mA). Operation is automatic. There are no further programming steps required. The values of P0L and P0H must be within the programmed scale range. The scale range is set by the SCAL and SCAH in the Secure menu.
PUMP RUN TIME OPERATION
The pump run time is indicated in hours of operation since the last time that the run time meter was reset for a specic pump. The Pump Run Time key on the front of the unit will display run time for both pumps when depressed. Run time for pump 1 is in the top display and pump 2 is in the lower display. To reset the pump run time go to the menu items P1rn and P2rn in the Secondary Menu. When in the corresponding menu item hold the
ENTER button for approximately two seconds. The display will blank out for about 1 second and the run time will display 0. These menu items can be locked out by the PrSt menu item in the Secure Menu.
OPTION 232, 485 SERIAL COMMUNICATION OPERATION
The serial communications options allow the control to be written to and read from a remote computer or other similar digital device. Communication is allowed either through a RS-485 (Option 485) port, or a RS-232 (Option
232) port.
Wire the communication lines as shown on page 5. Wiring for the RS-485 is run from control to control in a daisy chain fashion with a termination resistor (120 Ω) across the transmit and receive terminals of the last control in the chain. Set the RS-485 DIP switch for half or full duplex as appropriate for your application. The DIP switch is located on the communications board plugged into the center of the bottom board of the control.
Select the control address and communication baud rate with the Addr and bAUd menu items in the Secure Menu. THE BAUD RATE AND ADDRESS MENU ITEMS WILL TAKE EFFECT ON THE NEXT POWER UP OF THE CONTROL. BE SURE TO POWER CYCLE THE CONTROL BEFORE USING THE NEW BAUD RATE AND ADDRESS.
In operation, you have the option of preventing a write command from the host computer. To prevent the host from writing to the control change the L0rE menu item in the Secondary Menu to L0C. To allow the host to write commands to the control set L0rE to rE. (The host does have the ability to change the L0rE state, but it is not automatic.)
If your system depends on constant reading or writing to and from the host, you may wish to set the No Activity Timer (nAt) to monitor the addressing of the control. When the L0rE is set to rE and the nAt is set to any value other than 0FF, the control will expect to be addressed on a regular basis. If the control is not addressed in the time set by the value of nAt, then the control will display the error message CHEC LorE. To clear the message set
L0rE to L0C.

MENU SELECTIONS Notation Conventions for the Menus
Because of the number of features available in this control, information is included that may not apply to your specic control. All usable features are included in this book, but may not be used in your process. To increase clarity the following conventions are used:
1. Certain features or functions shown in this book are contextual. This means that Menu Items may or may not appear, depending on other Menu Item selections. Whenever this occurs, a notation is made in the Menu Item that ˝controls˝ or ˝directs˝ other menu items. If you are looking for a particular menu item and can’t nd it, check the menu item that is its ˝control˝ for proper setting.
2. The ˝#˝ symbol is used in two ways. It is used inside a group of characters to indicate which set point function (SP1 or SP2) is being affected. It is also used before a group of characters of a menu item to indicate that there may be more than one selection or value for that menu item.

ALARM TYPE AND ACTION
Caution: In any critical application where failure could cause expensive product loss or endanger personal safety, a redundant limit controller is required.
CAUTION
the alarm is to occur.
When setting the alarm value for a deviation alarm (A1t = dE or A2t = dE), set the difference in value from the Set Point (SP1H) desired.
Since the input for the MPC is driven from a transmitter, the input display can be programmed in different ways. Regardless of the position of the decimal point, a change of one in the right most digit is referred to as a count. For example, if there were no decimal point selected, a change from 235 to 236 is a change of one count. If the decimal point were selected at 0.0, a change of 23.5 to
23.6 is a change of one count.
When setting up an alarm for deviation the deviation is set in counts. For example if a low alarm is required to be 5 counts below the SP1H, then set A#Lo to -5. If a high alarm is required 20 counts above the SP1H, then set A#Hi to +20. If SP1H is changed, the alarm will continue to hold the same relationship as originally set.
When Alarm Power Interrupt, A#P, is programmed ON and Alarm Reset, A#rE, is programmed for Hold, the alarm will automatically reset upon a power failure and subsequent restoration if no alarm condition is present.
If Alarm Inhibit, A#iH is selected ON, an alarm condition is suspended upon power up until the process value passes through the alarm set point once. Alarm inhibit can be restored as if a power up took place by pressing both the INDEX and ENTER keys for 5 seconds.
When setting an alarm value for an absolute alarm (A1t = AbS or A2t = AbS), simply set the value at which
WARNING
HIGH ALARM, RESTORATION OF POWER WILL NOT CAUSE THE ALARM TO OCCUR IF THE PROCESS VALUE DOES NOT FIRST DROP BELOW THE HIGH ALARM SETTING. DO NOT USE THE ALARM INHIBIT FEATURE IF A HAZARD IS CREATED BY THIS ACTION. BE SURE TO TEST ALL COMBINATIONS OF HIGH AND LOW ALARM INHIBIT ACTIONS BEFORE PLACING CONTROL INTO OPERATION.
