ICON 100 SERIES USER GUIDE

EN2B-0002UK07 R0404

Note: In order to leave a configuration parameter unaltered during the modification

procedure, depress the SET key, after having stored the modified value of the

previous parameter, the controller displays the code of the parameter to be left

unaltered. In this manner the controller proceeds and shows the code and then the

value of the parameter following the unaltered one. The changes made relating to

time values are only effective after the currently running timed cycles end, while

changes to the set points are effective immediately.

5.8. Locking / Unlocking the Keypad

Keeping the UP and DOWN keys simultaneously depressed for 10 seconds makes

it possible to lock/unlock access to the configuration parameters menu. The

controller will signal this by either showing the blinking message "PoF” (push-button

OFF = keypad locked) or "Pon" (push-button ON = keypad unlocked). It is very

useful to lock the keyboard in order to avoid tampering with the configuration

parameter values by non-authorised personnel.

Note: The controller will default to “PoF” (keypad locked) if power is interrupted or

switched off.

5.9. Setting and Displaying the Real Time Clock

The Real-Time Clock (RTC) operates on a 24 hour cycle (00:00…23:50) on Icon

models: ICON-111SR, ICON-112SR & ICON-132SR.

1. The current time set in the RTC can be displayed by simultaneously depressing

and releasing the DEFROST and SET keys.

The display will show either two or three numbers. The first one or two numbers

represents the hours, the last number always represents the minutes (displayed

in multiples of 10).

Example: 24 = 02 hours and 40 minutes.

173 = 17 hours and 30 minutes.

2. By depressing the DOWN key it is possible to display the current hours

of the

clock. If you continue to press the key, the setting of the hours is modified and

the value increases in a progressively faster mode.

3. By depressing the UP key it is possible to display the current minutes

of the

clock. If you continue to press the key, the setting of the minutes is modified

and the value increases in a progressively faster mode.

Ten seconds after the last activation of the key, the displayed time disappears and

the display case / cold-room temperature re-appears again.
