Code Table: TY1: Relay 1 output alarm type 0: Upper limit alarm, temperature AL1, the relay is closed, (AL1-HY1), the relay is off. 1: Lower limit alarm, temperature AL1, the relay is closed, (AL1+HY1), the relay is off. 2: Upper and lower limit alarm. Temperature AL1, the relay is closed, HY1, the relay is closed. AL1: Relay 1 action value -40.0~130.0 HY1: Relay 1 return difference -40.0~130.0 TY2: Relay 2 output alarm type 0: Upper limit alarm, temperature AL2, the relay is closed, (AL2-HY2), the relay is off. 1: Lower limit alarm, temperature AL2, the relay is closed, (AL2+HY2), the relay is off. 2: Upper and lower limit alarm. Temperature AL2, the relay is closed, HY2, the relay is closed. AL2: Relay 2 action value -40.0~130.0 HY2: Relay 2 return difference -40.0~130.0 SEC: Relay action delay value 0-999 seconds When the relay AL1 or AL2 reaches the operating conditions, it will delay the action for SEC seconds. When it is 0, there is no delay. LC: Temperature deviation correction value -20.0~20.0 (display value = measurement value + LC) note: Please allow 1-3cm error due to manual measurement. pls make sure you do not mind before you bid.
