Alarm Mode Selectors (SW203: ALM1; SW204: ALM2)
Alarm mode selectors are provided on all Temperature Controllers. Alarm modes, listed in the following table, can be selected using this switch.
The switch is factory-set to position 2, i.e., the upper-limit alarm mode.

Key Protection Switch (SW101, PROTECT)
The key protection switch is factory-set to the OFF position. When the key protection switch is ON, the Level Key, Up and Down Keys, and
Auto-tuning Key cannot be operated. In effect, the E5EX is write-protected and the set values (such as the alarm value) can be only read out.
However, when pin 4 of the function selector (SW201, FUNCTION) is set to the ON position (i.e., SP (set point) protection is cancelled), only the
set temperature value can be changed.
Terminator Switch (SW206, TERMINATOR)
The terminator switches of all the Temperature Controllers on a network must be set to the OFF position, except the terminator switch of the
Temperature Controller working as the end unit (i.e. the Temperature Controller farthest from the host computer on a network). The terminator
switch is factory-set to the OFF position.
Note:
If the terminator is not designated correctly, the total current consumption will increase and communications errors could result.
Inputting Parameters
The Temperature Controller has three display levels 0, 1, and 2, in which only specific parameters can be set. Level 0 is the initial level and is
automatically entered at power application. To change the mode to set or change a different group of parameters, hold down the Level Key for 2
seconds minimum. The display level mode changes as shown below. Actual displays vary with models and switch settings. If a display does not
appear as expected, check your switch settings.
