d) All hour timers (defined by P5) must be housed in outputs. The value of P5 will be
interpreted as an output.
Motor Group Control
Allows up to four motors to be controlled in a group where primary responsibility will alternate to
ensure wear leveling. Hours of operation will be tracked in hours and tenths of hours.
Motor Group Control – P1 P2 P3 P4 P5
P1 = function:
start_primary 1
start_secondary 2
start_tertiary 3
start_quaternary 4
start_all 5
stop_primary 6
stop_secondary 7
stop_tertiary 8
stop_quaternary 9
stop_all 10
override_state_change 11
P2 = motor_count: how many motors in this group (1 - 4)
P3 = motor_start: Starting output pin for motors. Others will be assigned sequentially
P4 = override_start: Starting input pin for override control of motor. Others will be assigned
sequentially.
P5 = hours_start: Starting output pin for hour meters. Others will be assigned sequentially.
Note: Override (P4) refers to a switch or signal to place the motor in service or take it out of
service. When the motor is in service it operates automatically under the control of the
Control_Motor_Group function. When it is out of service it is not available as a part of the
group being controlled. A motor that is out of service can still be switched on and off
manually but its state will be unknown to the Control_Motor_Group function.
Example – Starting the primary pump at a pump station with two pumps starting on output pin 2
that are managed by override switches starting at input 4 and whose hours are tracked on
outputs starting at output 6.
Action: Motor Group Control
Parameters: 1 2 2 4 6
Example – Stopping all pumps at a pump station with two pumps starting on output pin 2 that are
managed by override switches starting at input 4 and whose hours are tracked on outputs starting
at output 6.
Action: Motor Group Control
