10. r is under setting temperature temperature difference and it stops heating when the temperature is over setting temperature temperature difference x Compressor delay when power on The compressor delay when power on is set by F20 for example 3 minutes the controller does not start the compressor within 3 minutes after power on x Compressor delay time The compressor delay time is set by F21 for example 3 minutes The controller contains a compressor halt calculagraph and it begins to time when compressor stops the program first check the calculagraph before booting the compressor next time the program will immediately boot the compressor if the calculagraph reach 3 minutes if the calculagraph doesn t reach 3 minutes it will boot again when the calculagraph reaches 3 minutes Thus you can ensure that the boot alternation is over 3 minutes after halt so it can prevent to breaking the compressor as a result of frequent boot oY Compressor running timly when temperature sensor is error When the temperature sensor is error in order to avoid that the goods in the coldroom destroy you can make the compressor continues to run with a setting on off rate It is set by F22 and F23 for example F22 20 F23 50 that when the temperature sensor is error the cycle is 50 minutes and the compressor stops for 40 minutes and runs for 10 minutes oY Auto defrosting principle The controller has 3 defrost start modes w
11. rs In addition it may stop when defrosting rest with F38 In spite of which mode fan state is only rested with F38 when defrosting In spite of which mode fan stops when external alarm occurs oY External alarm The controller can connect a switching value as external alarm source Pin 4 5 when the external alarm occurs the controller stops displays the alarm code A11 and generates alarm output External alarm signal has 5 modes F50 without external alarm always open unlocked always open locked always closed unlocked always closed locked Always open means in normal state external alarm signal is open if closed the controller will give an alarm Always closed is on the contrary Locked means that when external alarm signal becomes normal the controller is still in the alarm state and it needs to press any key to resume SY Probation time A probation time can be set F87 the controller can add up the running time after power is on if the accumulative running time is over the probation time the controller will stop and display the alarm code A99 if you want to eliminate the limit of probation time set the F87 to OFF also you can use the F86 to clear the accumulative running time and you can try to use it again The parameter F85 can be used to examine the accumulative running time of the controller hour oY Password In order to prevent irrespective persons from changing the parame
