(1) the unit of measurement depends on P2
(2) Properly set the parameters corresponding to the regulators after modifying parameter P2
(3) the parameter has effect even after an interruption in the power supply that occurs while the instrument is switched on
(4) the time established with the parameter is counted even when the instrument is switched off
(5) if parameter C1 is set to 0, the delay after the end of the cell probe error will be 2 min
(6) the parameter differential is 2.0 °C/4 °F
(7) if when the instrument is switched on, the condenser temperature is already above that established in parameter C7, then parameter C8 will not have effect
(8) the instrument stores the defroster interval count every 30 min; the modification of parameter d0 takes effect following the end of the preceeding interval or following the activation of manual defrosting.
(9) the display returns to normal operation when, at the end of defrosting (EVX201 only) or at the end of evaporator fan disactivation (in EVX203, EVX204, EVX214, EVX205 and EVX215 only), the cell temperature falls
below that at which the display was initally blocked (or if a temperature alarm is signaled)
(10) if parameter P3 is set to 0 or 2, the instrument will function as if parameter d8 were set to 0
(11) 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 compelete defrosting
.
(12) if parameter P3 is set to 0, the instrument will function as if parameter A0 were set to 0 but it will not store the alarm
(13) during defrosting and dripping and when the evaporator fan is stopped, the temperature alarms are absent, provided that these were signaled after the activation of defrosting
(14) during activation of the door microswitch input, the maximum temperature alarm is absent, provided the alarm was signaled after the activation of the input
(15) when power is restored, the alarm will always be signaled
(16) if parameter P3 is set to 0, the instrument will function as if parameter F0 were set to 2
(17) the parameter can also be modified using the procedure described in paragraph 4.8
(18) if parameter P4 is set to 0, the condenser fan will function in parallel with the compressor
(19) 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 disactived, the activation will not have any effect on the compressor
(20) the instrument stores the alarm once the time established in parameter i2 has expired; if parameter i2 is set to -1, the instrument will not store the alarm
(21) make sure that the time established with parameter i7 is less than that established with parameter i9
(22) to avoid damaging the unit connected to the instrument, change the parameter setting when the instrument is switched off
(23) if parameter u2 is set to 0, switching off the instrument 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 instrument will not 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 on).
13 ELECTRIC CONNECTION
13.1 Preliminary notes
With reference to the electrical wiring diagrams:
• the unit connected to and operated by the fourth outpt depends on parameter u1 (EVX204, EVX214, EVX205 and EVX215 only)
• the unit connected to and operated by the fifth outpt depends on parameter u11 (EVX205 and EVX215 only)
• the serial port is the port for communicating with the monitoring system (via serial interface, via TTL, MODBUS communications protocol) or by programming key ; the port must not be used for two different purposes
simultaneously.
13.2 EVX201 electrical wiring
13.3 EVX203 electrical wiring
13.4 EVX204, EVX214, EVX205 and EVX215 electrical wiring
13.5 Electrical wiring warnings
• do not use electric or pneumatic screwers on the terminal boards
• if the instrument was brought from a cold place to a hot one, humidity may condense inside the instrument; wait approximately one hour before switching on the power
• make sure that the power tension, frequency, and the electric operating power of the instrument are compatible with the those of the local power voltage
• disconnect the power before performing any type of maintenance operation
• do not use the instrument as a safety device
