and bicolor digital displays the current delay
Data Setting Storage Adopting EEPROM, the action mode of relay and data preset storing time not less than 10 years
Action Mode Of Relay Four kinds of modes(Remark 1)
Accuracy Voltage affects error, repetitive error less than ± 50PPM and preset error is 0
Signal Input Reset and pause signal input is contact or NPN (emitter to common terminal 1),
adopting photoelectric coupling solation, signal width should not less than 0.02 Sec

Remark 1 : Output relay can preset any of the four working modes,see the following table
 
Code Of Preset Mode Working mode instruction for outputting relay
H-. on;  d-.of Starting delay after power on, relay closes after reaching preset value
H-. of;  d-.of Not delay after power on, to make it work through panel reset key or bottom reset terminals,
relay closes after reaching preset value
H-. on;  d-.on Starting delay after power on, relay closes and it releases after reaching preset value
H-. of;  d-.on Not delay after power on,relay closes, to make it work through panel reset key or bottom reset terminals,relay releases after reaching preset value
 
To set the above four kinds of working modes for relay as the following operations:
for LT4I press reset without stop before power on, after power on,LED displays any of the above four codes,
to set the needed one via "∧" "∨" key,then press "set" to confirm, cut off the power and power on again.
