Menu Password
When the menu password is active, it is possible to review all of the control settings without having the password. When a password is activated and the user presses the menu key, two choices are available:
1)MENU (PASSWORD REQ)
2)CONTROL SETTINGS
By selecting choice #2 the user can go through the menu system and see all of the settings in the control but in this mode, the user cannot change any settings. If either the power-on or the menu passwords are forgotten, the user can reset the password by typing in 9999 when asked for the password. The KRYOS will display an 8- digit number. Call your distributor or Taylor-Wharton with the 8-digit number to obtain a unique 8-digit number to type into the control. When this number is entered, all passwords are cleared.
Serial Communications and RS-232 Settings
The KRYOS control system is designed with a 2-way serial communication feature. RS-232 (MENU, 6, 1) allows the user to configure the serial port to “talk” with other Data Terminal Equipment (DTE). The control can send data through it’s serial port to a computer, a printer or a modem. System logs, error logs or temperature logs are always available for download. In addition to downloading data, the control can accept commands through the serial port. Control settings can be viewed or changed at any time. Also remote diagnostics can be performed.
If the RS-232 is enabled the handshaking can be turned on and off. This feature allows two devices to communicate when sending data. Also the baud rate can be set for the following speeds: 300, 1200, 2400, 4800, 9600 or 19200 baud.
Time and Date Set
TIME AND DATE SET can be changed through the menu system. (MENU, 6, 2, 1). The date and time will be set at the factory to Central Time, USA.
User Access Logs
The USER ACCESS LOGS (MENU, 4, 3) track all personnel who enter the freezer by asking for an identification number when the lid is opened. When this feature is enabled, the control asks for an identification number any time the lid is opened. An entry is then recorded in the log indicating the time, date and identification of the person entering the freezer. The user has 30 seconds to enter an ID code (the 30 seconds is counted down on the screen). If an ID is not entered within the 30-second time frame, the log indicates that an unidentified user accessed the freezer. Identification numbers range from 00 to 99.
