- KEYBOARD FUNCTIONS

Enter: to activate the programming mode and to view and to confirm the new values.

Function: 1) to show the Haccp records; 2) pushed for 5 seconds, to start or stop manually the defrost (if LFc=0) without waiting dSd, or to switch on/off the controller (if LFc=1). The off mode, or stand-by, is stored in memory; 3) in programming mode, to quit the parameters menu without saving the new values (escape command); 4) during an alarm event, to switch off the optional internal buzzer and relay.

Up: 1) to display, for a few seconds, the probe 1 snap temperature; 2) during the programming mode, to scroll the parameters menu and to increase the value of the selected parameter.

Down: 1) pushed together with the Enter key, for 5 seconds, to lock / unlock the keyboard; 2) during the programming mode, to scroll the parameters menu and to decrease the value of the selected code.

Light on → compressor is running (output relay K1 is on, Act=0); Flashing → waiting for a time delay to switch on the compressor.

Light on → heater is running (output relay K1 is on, Act=1); Flashing → waiting for a time delay to switch on the heater.

Light on → defrost action is running.

The upper left point is flashing in programming mode and is lit on if an external contact is active (digital input) or during the stand-by mode. The number "1" indicates the current probe temperature shown on the display.

1.00 GENERAL DESCRIPTION AND INSTALLATION NOTICE

The RC31 models are controllers specifically designed to manage static refrigerating units, for positive (or normal) temperatures. Simply modifying a parameter, it is possible to select between direct and inverse action, to control also heating appliances.

The controllers have 1 analog input for ntc/ptc temperature probe and 1 output relay for cooling or heating control, optionally a digital-input for an external switch and optionally 1 alarm relay or buzzer. In cooling mode, it performs defrost by stopping the compressor for a defined time. RC31 detects temperature alarm conditions referred to the temperature probe, storing into its memory the last tree events (Haccp feature). Through the TTL port, an external master device can read and write the RC31 registers, in order to monitor and change its functioning.

1.10 Installation notice

The installation must be done only by specialized personnel in according to the rules in force in the country where the controllers are used. The instrument is conceived for controlling and regulation, not for safety function. It must be installed in a place protected from extreme vibrations, impact, water, corrosive gases, and where temperature and moisture do not exceed the maximum rating levels indicated in the specifications. The probe is not waterproof, it should be placed with its head upward, so that drops would not penetrate into the bulb and damage the sensor. Maintain the length of the electrical wires as short as possible in order to keep the noise picked by them at low level; otherwise a shielded wire will be needed, and the shield will be connected to the ground. Pay attention to connect correctly the probe PTC300 type, it is polarized: cathode must be at ground level.

1.20 ELECTRICAL WIRING

We recommend to protect the power supply of t he controller from electrical noise, spikes and especially from voltage surges and drops. This can be easily done following these recommendations:

-separate the power supply of the loads (compressor, heaters, fans) from the power supply of the controller. This alleviates problems related to voltage dips that can arise during the switch-on of the loads, that may disturb the controller's microprocessor causing unexpected resets.

-the cables of the probes and the ones of the controller supply or the loads must be separated, to reduce spikes and noise on the sensor. This improves the stability of the reading and it also makes the commutation of the device more accurate.

1.30 CRITICAL ENVIRONMENT

For applications in heavy industrial environment these rules should be followed.

- After having identified the source of noise spikes, it is recommended to apply a line filter to the source in question of the type specifically designed to solve EMC (Electromagnetic compatibility) related problems. Sometimes it may be sufficient an RC type filter, also called «snubber», connected in parallel to the external relay coils, or circuit breakers.

- An independent power supply should be used to power the device in extreme conditions.

ATEX reserves the right to make changes without further notice to any products herein to improve reliability, function or design.

3.20 Menu Level 2 - Adjust all the other OPERATING PARAMETERS

1) Press the Enter key “-” and hold it for 6 seconds. The upper point will flash to indicate programming mode entering. If no password is set (PSS=0), the code of the first variable SHy will appear, go to point 3. If password is set, will appear “PAS” request;
2) (password request) Press and release the Enter key “-”, “0” will be shown; press “▲” to enter the right password value and then press and release the Enter key to confirm it. If the value entered does not match the stored password (PSS), the controller exits the programming mode;
3) (SHy showed) press “▲” or “▼” to scroll all the parameter codes;
4) While a code is displayed press and release the Enter key “←” to view its content, adjust it by pressing “▲” or “▼”;
5) Press and release “☐” to confirm the data, after 15sec. the RC31 will quit the programming mode and the data will be stored in the memory.

WARNING:

• the instrument must not be reset before leaving the programming mode, otherwise the new setting will be lost;
• if the "Function" key is pressed during the programming mode, the user will exit the progr. mode without saving, RC31 will lose the new setting;
• the controller automatically interrupts any setting operation if any push-button isn't pressed for at least 15 seconds and store the current data;
• after having modified any parameter the controller must be restarted (unplug and plug again) .

3.30 Keyboard locking

Press and hold both the Enter key “J” + the Down key “▼” for 6 second, in order to lock and unlock the keyboard (the upper-left point will flash).

If the controller shows "Pof" it means the keyboard is locked, if it shows "Pon" the keyboard is unlocked.

When the keyboard is locked it is possible to view any parameters value but not to change them.

3.40 How to show the stored alarm temperatures (Haccp feature)

The RC31 stores the last 3 temperature alarm events: the temperature of probe 1 has been lower than ALo or higher than AHi.
- when the controller is showing the temperature (i.e. not in programming mode), press and release the "Function" key;
- it will show "HcP" (Haccp) and, if any alarm data are stored, it will show "AL1", min/max temperature reached and for how long (minutes) the temperature 1 was over ALo or AHi, then "AL2", min/max alarm ... . AL1 is referred to the most recent event. AL3 is the oldest.

When the RC31 is showing the Haccp data, pressing the "Function" key for 5 seconds will erase the alarm data stored (it will show "--").

The controller will show only data for alarms of events which have come back to normal. If an alarm is running, it could be ended decreasing the ALo or increasing the AHi value. At the end of an alarm the RC31 stores the Haccp data in its memory.

During the defrost actions there is no alarm recording. RC31 doesn't have a battery inside, if power fails occurs it does not check/record any data.

Changing the temperature measure unit ("unt" param.), the logged temperatures / parameters values reflect unit set in the past (not convert).

ALo	Low temperature threshold alarm (ex LoA). If the temperature goes below this value (ALo-0,4), the controller activates an alarm signal on the display and starts recording the minimum temperature and the duration of the alarm (Haccp function). Also it switches on internal buzzer and alarm relay, if present (optional).	AtP=0, -50..(AHi-1) AtP=1, -50 .. -0.5°C	-40 °C
AHi	High temperature threshold alarm (ex HiA). If the temperature goes up over this limit value (AHi+0,4), the controller activates an alarm signal on the display and starts to record the max temperature and the time duration of the alarm signal. Also it switches on internal buzzer and alarm relay, if present (optional).	AtP=0 (ALo+1)..150 AtP=1 0.5 .. 285°C	110 °C
Adi	Alarm delay at the power on. The RC31 does not check any temperature alarm for Adi hours from the power on.	0 .. 10 hours	0 h
ALd	Alarm delay on running time.The temperature must be in the alarm range for ALd minutes to switch on the alarm signal.	0 .. 120 minutes	0 m
AdF	Alarm delay after defrost. After the end of any defrost, the RC31 waits AdF minutes before checking any temp. alarm.	0 .. 180 minutes	0 m
Ad0	Alarm delay after de-activation of the external contact (digital input).I.e.: after closing the room door, the RC31 waits Ad0 minutes before checking the temperature for alarm.	0 .. 240 minutes	0 m
Ad1	Alarm delay from the activation of the external contact. The delay count starts immediately without waiting Eid.I.e.: after opening the room door, the RC31 waits Ad1 minutes before checking the temperature for alarm	0 .. 120 minutes	0 m

Note: The alarm signal management is disabled during the defrost actions (no start, nor stop alarm).
When AtP=1, ALo & AHi are always referred to the SEt value, also if St2 is activated by an external input.

4.30 DEFROST parameters

The RC31 does not perform any defrost action when inverse action is set (if act=1).

Param. code	Description Range Default
dPt	Defrost time period. It is the period of time between two defrost actions.	1 .. 240 (dtS)	6 h
ddt	Defrost duration. It is the duration of each defrost action. If ddt=0 the defrost function is disabled.	0 .. 240 (dtS)	30 m
dtS	Defrost time scale (ex tiS). It changes the time scale of dPt and ddt.0: dPt hours, ddt minutes; 1: dPt minutes, ddt seconds;	0 .. 1 0
dSd	Defrost start delay. It is a delay between the time to start of the defrost action and its real beginning (switch off of the output). At the power on of the controller, it starts the first defrost action after dPt hours + dSd minutes (and the successive starts after dPt). If an external contact activates the defrost action (if Eio=±4), it starts after dSd minutes.	0 .. 120 minutes	0 m
dAd	Delay to switch on the compressor after a defrost end (ex Add). Dripping Time. After a defrost cycle, the compressor is stopped to assure dripping of possible water still present in the evaporator.	0 .. 120 minutes	0 m
ddd	Displayed during the defrost action.0: the temperature at the defrost start; 1: the message “dEF”; 2: the SET value; 3: the currently temperature.When 0, 1, 2, the value will be shown on the display until the controller will have reached again the Set Point value.	0 .. 3 0

4.40 Various parameters
