A.4 Key function and parameter setting
3. If the measuring loop of temperature controller is disconnected,-OP- will blink in PV and fault relay J5 will be
connected.
4. If input signal is beyond the measurement range of temperature control:
If beyond the upper limit, -OH- will blink in PV and fault relay J5 will be connected.
If beyond the lower limit, -OL- will blink in PV and fault relay J5 will be connected.
5. Fan operation: When green indicator light is on, fan control relay J3 will be connected.
6. Over-temperature alarm: When yellow indicator light is on, over-temperature alarm relay J2 will be connected.
7. Over-temperature tripping: When temperature value blinks in PV, over-temperature tripping relay J1 will be
connected.
8. Implications of displayed value in SV:
SV
Working mode of temperature controller
Remarks
PH X
3-phase(4-way) circular display mode, 3-phase(4-way)
temperature value is lower than alarm value.
X and X’ stand for phases A, b and C,
(d-way)
X refers to the phase sequence
under measurement and display.
X’ refers to over-temperature phase
sequence.
X’ X
X’-phase temperature in 3-phase(4-way)temperature
value is beyond the limit.
HH X
3-phase(4-way)temperature value is normal and fan is
under the manual start mode.
HX’ X
The fan is under the manual start mode and X’-phase
temperature is beyond the limit.
UU X
Temperature controller is under the maximum value
display mode.
HU X
Temperature controller is under the maximum value
display mode while the fan is under the manual start
mode.
1. Function of key
(1) SET KEY
Under normal working mode when the key is pressed, temperature controller will switch to the parameter setting
mode and pressing the key in setting will come to the next step.
(2) ( KEY
Under the setting mode, pressing the key once will add one to the parameter displayed and if the key is held
on, the number will be increased quickly. Under normal working mode pressing the key will change the fan from
manual mode to auto mode or vice versa.
(3) ( KEY
Under the setting mode, pressing the key once will decrease one from the parameter displayed and if the key
is held on, the number will be decreased quickly. Under normal working mode pressing the key will change the
