Fn 18 LOW/HIGH Temperature and Timer ALARM Relay Action.
1. In Low/High Temperature Alarm mode:
When set, this function enables the internal relay to be switched OFF when the Temperature ALARM occurs and
ON when there is NO ALARM condition.
When this function is NOT SELECTED the internal relay will ONLY be switched OFF in response to the HIGH
Temperature or Timer ALARM and ON when the Temperature is LOWER than the PRESET for HIGH ALARM
even if it is lower than the preset LOW ALARM.
2. In Timer/Stopwatch Alarm mode:
When set, this function enables internal relay to be switched OFF when the Timer is NOT Active or when the Timer
ALARM occurs (count-down finished). The internal relay will be switched ON when the counting is pending.
When this function is NOT SELECTED the internal relay will ONLY be switched ON when the Timer ALARM occurs
(counting finished).
See also Fn 16, 17, 37.
Fn 19 Temperature display with Decimal Point. Almost always may be used only in 6 digits displays or special feature.
Fn 20 MIN/MAX Temperature Memory display Enable.
Fn 21 BCD Time Code Slave receiver Enable. (compatible with the Simplex BCD code for 50Hz and 60Hz line)
Fn 22 POWER LINE FREQUENCY BASED TIME AUTO-CORRECTION Enable. Adjusts automatically to 50/60Hz line.
Fn 23 POWER LINE CARRIER SYNC Enable. Requires the Master clock signal presence in the power line.
( Also see Fn 11,12,13,14 )
Fn 24 MANUAL BRIGHTNESS CONTROL Enable.
When set, this function allows for the manual control of the display brightness by activating the “NXT” key. Once set,
the brightness level will be memorized even if this function is subsequently disabled.
Fn 25 AUTO-DIMMING BRIGHTNESS CONTROL Enable (optional ).
Fn 26 INVERTED SECONDS display for 6 digits model. Do not alter this setting.
Fn 27 INTERNAL TEMPERATURE PROBE selection for the operation in the Thermostat and Thermometer modes and
Temperature Min/Max memory functions. If not enabled, the EXTERNAL sensor is used.
Fn 28 LOOPING TIMER ENABLE. For both UP and DOWN counting, the timer/counter will reset and restart itself
automatically upon reaching the PRESET value. See also Fn 87.
Fn 29 Hi/Lo Temperature Alarm Display Enable. ( see also Fn 27 ).
Fn 30 Hi/Lo Temperature Control and Alarm Mode Enable. ( see also Fn 27 ).
Fn 31 EVENT UP/DOWN COUNTER mode selection. (Function Fn 39 must also be enabled)
When selected, this function enables the Counter of Pulses presented at the COUNTER INPUT terminal if the
External Counter/Timer Inputs are enabled (by Fn 36) or “Clocked“ by the remote control UP and DN keys if the
external inputs are not enabled or if the function Fn 59 is enabled.
The Counter Result (count) display is enabled by enabling Fn 7.
The Counter operates as UP-COUNTER when the preset count is equal 000000 or as UP and DOWN-COUNTER
when the preset is different than 000000 but will not allow for clocking down from the count 000000.
NOTE that in the EVENT COUNTER mode the range is 9999 if the 6-digit display format is not selected (see Fn 9 ).
Fn 32 2-WIRE (RS232/485) MASTER CLOCK Mode for the Master-Slave synchronized system.
(also see Fn 46, 53, 54, 55, 88, 89 )
When enabled, this mode will cause the clock to function as a Synchronized System Master Clock.
See also functions Fn 33 and Fn 34 .
NOTE: This mode may be used when one of the External Sync Communication options is installed.
Fn 33 2-WIRE (RS232/485) SLAVE clock Mode in DISPLAY REPEAT synchronized system.
All display data will be copied as sent from the Active Master clock display in real time. The Time data will not be
updated in the Slave clock unless the function Fn 34 is also enabled. See also Fn 88, 89.
Only the clock Preset/Programming mode can override this mode.
In some Master-Slave modes this function may also be used to enable certain Repeater modes ( see Fn53 ).
NOTE: This mode may be used when one of the External Sync Communication options is installed.
Fn 34 2-WIRE (RS232/485) SLAVE clock Mode in TIME synchronized system. (also see Fn 46, 88, 89)
Only the time data will be synchronized in this mode. All other local options and modes may be still selected.
