LED
MAN : Lights in the MANUAL mode, and goes out in the AUTO mode.
PRG : Lights in the program setup state. Otherwise, this LED is out.
• Upper display
In the basic display state, displays PV and other values.
In the parameter setup state, displays the item code.
• Lower display
In the basic display state, displays SP, time, output and other values.
In the parameter setup state, displays the item setting value.
• Low battery voltage LED
BAT: Blinks when the battery voltage is low. Otherwise, this LED is out.
• Control/output state LED
AT: Blinks during auto-tuning, and lights during smart-tuning. Otherwise, this LED is
out.
OT1: When relay or voltage are assigned to output 1, lights when output is ON and goes
out when output is OFF. In the case of 2G output models, lights when the open-
side relay is ON and goes out when the relay is OFF.
Lights when current output is assigned to output 1.
OT2: When relay or voltage are assigned to output 2, lights when output is ON and goes
out when output is OFF. In the case of 2G output models, lights when the closed-
side relay is ON and goes out when the relay is OFF. Lights when current output
is assigned to output 2, and goes out when auxiliary output is assigned to output 2.
OT3: Out
• Basic indicator LEDs
PV: Lights during PV display. Otherwise, this LED is out.
SP: Lights during SP display. Otherwise, this LED is out.
OUT: Lights during output display. Otherwise, this LED is out.
TM: Lights during time display. Otherwise, this LED is out.
CYC: Lights during cycle display. Otherwise, this LED is out.
CH1: Out
CH2: Out
• Event LEDs
EV1, EV2, : • In the basic display state or parameter setup state, light when each of
EV3 events1 to 3 are ON, and go out when OFF.
• In the program setup (programming) state, light when each of the items
for events 1 to 3 are displayed. Otherwise, these LEDs are out.
T1, T2, T3, : • Light when each of time events 1 to 5 are ON, and go out when OFF.
T4, T5 • In the program setup (programming) state, light when each of the items
for time events 1 to 5 are displayed.
Otherwise, these LEDs are out.
• Profile display
Displays the tendencies (rise, soak, fall) of the program pattern.
Blinks during G.soak standby, and lights successively after the power is turned ON.
