1ST SET POINT DISPLAY

Key functions are as follows:

INDEX: Pressing the INDEX key advances

the display to the next menu item. May also be used in conjunction with other keys as noted below.

UP ARROW: Increments a value, changes a menu item, or selects the item to ON. The maximum value obtainable is 9999 regardless of decimal

point placement.

UP ARROW AND ENTER: Pressing these keys simultaneously brings up the secondary menu starting at the SP1H menu item. Pressing these keys for 5 seconds will bring up the secure menu.

DOWN ARROW: Decrements a value, changes a menu item, or selects the item to OFF. The minimum value obtainable is -1999 regardless of decimal point placement.

ENTER: The ENTER key is used to store the value of menu items once they are changed to a new value. If the ENTER key is not pressed after changing the value the item will revert to the previously stored value.

6

INDEX and DOWN ARROW: Pressing these keys simultaneously will allow backing up one menu item, or if at the rst menu item they will cause the display to return to the primary menu. If an alarm condition has occurred, these keys may be used to reset the alarm.

INDEX and ENTER: Pressing these keys simultaneously and holding them for 5 seconds allows recovery from the various error messages. The following

menu items will be reset:

ALiH: Alarm inhibit CHEC CAL: Check calibration error

Correct the problems associated with the above conditions before using these reset keys. More than one error could be present. Caution is advised since several

items are reset at one time.

The Home Display

The home display is the normal display while the control is operating. If no errors or functions are active, the HOME display will indicate the Process Variable (the level that is being measured) on the top display and the SP1H value, Pump 1 On Set Point, on the bottom display.

Error messages may over-ride the HOME display. See ERROR MESSAGES on page 12.

While in the Secondary Menu, if no key is pressed for a period of 30 seconds, the display will return to the HOME position displaying the process value. While in the Secure Menu, if no key is pressed for a period of 60 seconds, the display will return to the HOME position displaying the process value. Outputs are disabled (turned off) when the Secure Menu is active.

Security Level Selection

Three levels of security are provided. The SECr menu item security level may be viewed or changed at any time regardless of the present security level in the Secure menu. The display shows the current security level. To change security levels change the password value using the UP ARROW or DOWN ARROW keys and pressing the ENTER key. Refer to the password table (following) for the correct value to enter for the security level desired.

To set the access level to, for example, 2, at the SECr menu item press the UP ARROW key until the upper display shows the password, 1101. Press the ENTER key. The display will blink, and return with the level value, 2, in the upper display.

The password values shown in the table cannot be altered. Retain a copy of these pages for future reference. This is the only reference made to password values in this instruction book.

LEAD/LAG OPERATION

The Mercoid 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® MPCJR 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 LdLg.

Lead/Lag On

After installation, set the SP1H to the high level (pump on point) for standard operation. Set SP1Lto 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.

OPERATION RV, RC ISOLATED ANALOG RETRANSMISSION

The analog retransmission option allows the Process Variable or the Set Variable to be sent as an analog signal to an external device. The signal may be either 0-10 VDC (option RV) or 0 (or 4)-20 mA DC (option RC). The output may be changed in the eld from one to the other by the toggle switch located on the top printed circuit board.

®

MPCJR pump controller is designed

Wire the output as shown on page 3.

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 Secondary Menu set POL for the the scale value that will be represented by the low end of the analog signal (0 V or 0 mA). Set POH for the scale value that will be represented by the high end of the analog signal (10 V or 20 mA).

If you require a suppressed scale or output, you may use the following equations to determine the proper settings for POL and POH.

K= (Highest desired scale reading - Lowest desired

scale reading)/(Maximum desired analog signal -

Minimum desired analog signal).

POH= ((Maximum possible analog output - Maximum

desired analog signal) *K) + Highest desired analog reading.

POL = Lowest desired scale reading - ((Minimum desired

analog output) *K).

Operation is automatic. There are no further programming steps required.

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 7. 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 LOrE menu item in the Secondary Menu to LOC. To allow the host to write commands to the control set LOrE to rE. (The host does have the ability to change the LOrE 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 LOrE is set to rE and the nAt is set to any value other than OFF, 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

LOrE to LOC.

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

HIGH

D

CAUTION

safety, a redundant limit controller is required.

When setting an alarm value for an absolute alarm (A1t =

AbS or A2t = AbS), simply set the value at which 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 MPCJR 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.

The following diagram (below) shows the action and reset functions for both absolute and deviation alarms.

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#Pi, 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.
