EVCO S.p.A. | Code 104R200E114 | Page of 10 | PT 14/13 | version 1.1
(13) the display restores normal operation when, on conclusion of evaporator fan standstill, the cell temperature drops below that which has blocked the display (or if a temperature
alarm occurs)
(14) in the EVR221, EVR231, EVR261 and EVR271 models, the maximum value of parameter d8 is 1
(15) if parameter P3 is set to 0 or 2, the device will function as if parameter d8 were set to 0
(16) if when defrosting is activated, the operating duration of the compressor is less than the time established with parameter d5, the compressor will remain on for the amount of time
necessary to complete defrosting.
(17) if parameter P3 is set to 0, the device will function as if parameter A0 were set to 0 but it will not store the alarm
(18) during defrosting and dripping and when the evaporator fan is stopped, the temperature alarms are absent, provided that these were signalled after the activation of defrosting
(19) during activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signalled after the activation of the input
(20) parameters F13 and F14 have effect when the compressor is off
(21) parameters F13 and F14 have effect when the compressor is on
(22) if parameter P3 is set to 0, the device will function as if parameter F0 were set to 2
(23) parameters F13 and F14 have effect when the evaporator temperature is below the temperature established with parameter F1
(24) parameters F13 and F14 have effect when the compressor is on and the temperature of the evaporator is below the temperature established with parameter F1
(25) the parameter can also be modified using the procedure described in paragraph 4.2
(26) if parameter P4 is set to 0, the condenser fan will function in parallel with the compressor
(27) the condenser fan is off when the temperature of the condenser drops below the temperature established with parameter F11 on condition that the compressor is off
(28) if the parameter i0 and parameter i5 are set at the same value, the effect will be caused by the activation of at least one of the inputs (until both inputs are deactivated)
(29) the compressor is switched off 10 sec after the activation of the input; if the input is activated during defrosting or when the evaporator fan is deactivated, the activation will not
have any effect on the compressor
(30) the device stores the alarm once the time established in parameter i2 has expired; if parameter i2 is set to -1, the device will not store the alarm
(31) make sure that the time established with parameter i7 is less than that established with parameter i9
(32) to avoid damaging the unit connected to the instrument, change the parameter setting when the device is switched off
(33) if parameter u2 is set to 0, switching off the device may cause the cell light and/or the auxiliary output to switch off (the next time the instrument is switched on the unit connected
will remain switched off); if parameter u2 is set to 1, switching off the device will not cause the cell light or the auxiliary output to switch off (the next time the instrument is switched
on the unit connected will remain switched on).
(34) the resistors are switched on when the temperature of the cell drops below the “work set-point + u7” and are switched off when the temperature rises above the “work set-point
+ u7 + 2 °C/°F”.
