SINGLE WELL CONTROLLER
Clearing Report Values = ☛
SET 10
The display shows:
ZERO ALL TOTALS
ON=YES OFF=NO
Press the ON button to clear all of the valve and plunger
counts (READ 04 and READ B4) and total times (READ 07
and READ B7).
This option does not clear the Plunger Travel Time History
(READ 06) and the Time Open and Closed History (READ
19). History information is always available.
Note: Press the OFF button to exit the Clearing Report
Values function without clearing any of the report values.
Time Open and Closed History = ☛
READ 19
This report provides information about the last 10 times
the A-valve was open, and the last 10 times the A-valve
was closed.
OPN-0 and CLS-0 show the most recent open and „
close information.
OPN-1 and CLS-1 show the 2nd most recent open and
„
close information.
OPN-9 and CLS-9 show the 10th most recent open
„
and close information.
Example:
OPN-0 O 00:20:00
CLS-0 C 00:15:00
OPN information shows:
How long the A-valve was open. Time Open includes: „
OPEN TIME ƒ
DELAY TIME (SALES) ƒ
DELAY CLOSE TIME (if any) ƒ
Time Open does
not
include B OPEN TIME (if any).
A letter that explains why the A-valve closed: „
F = low flow rate input or critical flow K value input ƒ
G = switch gauge input ƒ
H = high sales line pressure input ƒ
L = low sales line pressure input ƒ
M = manual close ƒ
O = open time ran out ƒ
S = increase in casing pressure input ƒ
U = drop in casing pressure input ƒ
CLS information shows:
How long the A-valve was closed
„
A letter that explains why the A-valve opened:
„
C = CLOSE TIME counted down to zero
ƒ
D = differential open pressure input
ƒ
M = manual open
ƒ
R = load factor input
ƒ
T = casing time input
ƒ
Note: If the A-valve opens because a close input stops,
there is no letter. For example, the A-valve closes in
response to a close input caused by low or high sales line
pressure. When the sales line pressure returns to normal,
the A-valve opens. The CLS information does not include
a letter.
Operating Mode Report =

Battery Status Report =
☛ READ 00
This report displays the current voltage of the battery and
the solar panel.
Example:
BATTERY = 7.00V
SOLAR = 9.24V
Sensor Status =
☛ READ 09
This report shows whether the sensor is ON or OFF.
Note: The sensor must be ON to read the sensor input.
When using the Time operating mode, you can set the
sensor to OFF. PCS recommends setting the sensor to off
only if you are not running a plunger.

This report displays the chip and software version
numbers.
Example:
VERSION 138-41
Modbus Address Report = ☛
READ 22
This report displays the controller’s modbus address.
Example:
MODBUS ADDR:005
Important! Do not change the modbus address.
