46 AO1 COMMAND Controls Analog Output 1.
Parameter 1501 must be set to this value for FLN to have this
control.
0135
(COMM
VALUE 1)
47 AO2 COMMAND Controls Analog Output 2.
Parameter 1507 must be set to this value for FLN to have this
control.
0136
(COMM
VALUE 2)
48 RESET RUN
TIME Commanded by FLN to reset the cumulative run timer (1 =
RESET, 0 = NO).
The control input is rising-edge sensitive, so, once the
command is issued, this point automatically returns to its
inactive state. This “momentary” operation avoids any need
for an explicit command to clear the point before a
subsequent reset can be issued.
49 RESET KWH Commanded by FLN to reset the cumulative kilowatt-hour
counter (1 = RESET, 0 = NO).
The control input is rising-edge sensitive, so, once the
command is issued, this point automatically returns to its
inactive state. This “momentary” operation avoids any need
for an explicit command to clear the point before a
subsequent reset can be issued.
50 PRC PID GAIN Sets the proportional gain of the active Process PID set, as
selected by Point 54, PRC PID SEL (1 = SET2, 0 = SET1). 4001 (SET1)
4101 (SET2)
51 PRC PID ITIM Sets the integration time of the active Process PID set, as
selected by Point 54, PRC PID SEL (1 = SET2, 0 = SET1). 4002 (SET1)
4102 (SET2)
52 PRC PID DTIM Sets the derivation time of the active Process PID set, as
selected by Point 54, PRC PID SEL (1 = SET2, 0 = SET1). 4001 (SET1)
4101 (SET2)
53 PRC PID DFIL Sets the time constant for the error-derivative of the active
Process PID set, as selected by Point 54, PRC PID SEL
(1 = SET2, 0 = SET1). 4004 (SET1)
4104 (SET2)
54 PRC PID SEL Selects the active Process PID set (1 = SET2, 0 = SET1). 4027
55 EXT PID GAIN Sets the proportional gain of the External PID controller. 4201
56 EXT PID ITIM Sets the integration time of the External PID controller. 4202
57 EXT PID DTIM Sets the derivation time of the External PID controller. 4203
58 EXT PID DFIL Sets the time constant for the error-derivative of the External
PID controller. 4204
59 LOCK PANEL Command by FLN to lock the panel and prevent parameter
changes (1 = LOCK, 0 = UNLOCK). 1602
60 INPUT REF 1 Sets Input Reference 1.
Parameter 1102 must be set to COMM for FLN to control this
value.
61 INPUT REF 2 Sets Input Reference 2.
Parameter 1106 must be set to COMM for FLN to control this
value.
62 EXT PID STPT The setpoint for the External PID controller.
The function of this point requires parameter 4210, PID
Setpoint Select, to be set to 19 (Internal).
