LEAD/LAG OPERATION
The Mercoid MPC pump controller is designed to easily operate a pair of pumps in
the most efficient 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,
SSPP11HH
and
SSPP11LL
control pump 1 and
SSPP22HH
and
SSPP22LL
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
LLddLLgg
.
Lead/Lag On
After installation, set the
SSPP11HH
to the high level (pump on point) for standard opera-
tion. Set
SSPP11LL
to the low level (pump off point). Set the
SSPP22HH
to the level where
you want BOTH pumps to turn on (emergency pump on). Set the
SSPP22LL
to the level
where you want the second pump to turn off (emergency pump off).
The controller will not allow you to set
SSPP11HH
below
SSPP11LL
,
SSPP11LL
above
SSPP11HH
,
SSPP22HH
below
SSPP22LL
, or
SSPP22LL
above
SSPP22HH
. The controller will not allow you to set
any set point or alarm point above or below the programmed scale. No error mes-
sages 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
SSPP11HH
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
SSPP22HH
point, both pumps will be turned on until the
SSPP22LL
point is reached, where
one of the pumps will turn off. When
SSPP11LL
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,
SSPP11HH
and
SSPP11LL
control pump 1 and
SSPP22HH
and
SSPP22LL
con-
trol pump 2. There is no alternating function.
SEAL FAILURE OPERATION
The Mercoid MPC Pump Controller is designed to work with most types of sub-
mersible pump moisture sensors to detect outer seal failure. Most often the mois-
ture sensor is a conductance device that detects moisture in the oil chamber indicat-
ing 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 ohms adjustable in 10K ohm steps, and is set with
Secondary menu items
SSFFSS11
and
SSFFSS22
. When the resistance of the moisture
sensor decreases below the resistance set point the MPC controller goes into the
programmed seal failure mode.
11
L-20 12/29/04 8:47 AM Page 11

In the Secure menu the value of
PPSSFF
is programmed for the action of the MPC
based on the condition of a seal failure. If set to "
AAUUttOO
", 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
PPSSFF
is set to “
rrEESS
”, when pump moisture sensor indicates that there is a seal
failure condition then the corresponding pump seal failure lamp is lit on the con-
troller. 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 val-
ues of
PP11SSFF
and
PP22SSFF
in the Secondary menu. The item
PP11SSFF
or
PP22SSFF
will
display
FFAAIILL
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 pro-
tection of the pump. The thermostat has a preset value from the pump manufactur-
er 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
PPOOTT
is programmed for the action of the MPC
based on the condition of the over temperature. When the pump temperature sen-
sor 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
SSPP11HH
and
SSPP11LL
set points.
If
PPOOTT
is set to "
AAUUttOO
" then the pump will be automatically placed back into serv-
ice and the lamp turned off when the over temperature condition has ceased. If set
to “
rrEESS
” then the pump will remain out of service and the lamp lit until the corre-
sponding manual reset
PP11OOtt
or
PP22OOtt
is reset in the Secondary menu (described
in the next paragraph). The pump cannot be brought back into service until the
12
L-20 12/29/04 8:47 AM Page 12

over temperature condition has ceased.
Once the pump has cooled down the MPC Pump Controller can be reset with the
values of
PP11OOTT
and
PP22OOTT
in the Secondary menu. The item
PP11OOTT
or
PP22OOTT
will
display
FFAAIILL
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 condi-
tion then the display will revert to “----“.
ANALOG RETRANSMISSION OPERATION
The analog retransmission allows the Process Variable to be sent as an analog sig-
nal to an external device. The signal may be either 2 to 10 VDC (option RV) or 4 to
20 mADC (standard). The output may be changed in the field 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 5.
To set up the analog retransmission, first determine the scale range that the analog
signal will represent. The maximum scale is 9999 counts. In the Secure menu set
PPOOLL
for the scale value that will be represented by the low end of the analog signal
(2 Volts or 4 mA). Set
PPOOHH
for the scale value that will be represented by the high
end of the analog signal (10 Volts or 20 mA). Operation is automatic. There are no
further programming steps required. The values of
PPOOLL
and
PPOOHH
must be within
the programmed scale range. The scale range is set by the
SSCCAALL
and
SSCCAAHH
in the
Secure menu.

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 ohms)
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 bot-
tom board of the control.
Select the control address and communication baud rate with the
AAddddrr
and
bbAAUUdd
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
LLOOrrEE
menu
item in the Secondary Menu to
LLOOCC
. To allow the host to write commands to the
control set
LLOOrrEE
to
rrEE
. (The host does have the ability to change the
LLOOrrEE
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 (
nnAAtt
) to monitor the addressing of the con-
trol. When the
LLOOrrEE
is set to
rrEE
and the
nnAAtt
is set to any value other than
OOFFFF
,
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
nnAAtt
, then the control will display the error
message
CCHHEECCLLOOrrEE
. To clear the message set
LLOOrrEE
to
LLOOCC
.

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 specific control. All usable features are included in this
book, but may not be used in your process. To increase clarity the following con-
ventions 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
find 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.
