Operation; Setting Regulation Parameters - Vemer FHT Series User Manual

[DF1] and dead band [DB1] for output
1, and all parameters on the alarm menu
for output 2. The maximum alarm trips
when the value [ST1]+[HIA] is reached
and is disengaged on reaching value
[ST1]+[HIA]-[DFA]. The minimum alarm
trips when the value [ST1]-[LOA] is
reached and is disengaged on reaching
value [ST1]-[LOA]+[DFA].
When only one output is provided, it will be reserved for the alarm with the same
functions.
Normal operation
Operation when parameters are not being programmed/confi gured.
When in this status, the device effects regulation based on the temperature
measured and the parameters set. The information displayed is:
• Temperature measured by the sensor
• Status of output OUT1 and, in devices with two outputs, OUT 2

SETTING REGULATION PARAMETERS

There are two types of programming for regulation parameters:
- Simple programming
- Advanced programming
Note: to restore default factory-set values, turn on the device while
pressing the "OK" key.
Simple programming
To change parameters in the Regulation menu [REG] only. This programming is
accessed by pressing the"OK" key.
Depending on the selected operating mode, the following parameters can be
confi gured (see System menu [SYS]):
– set, differential, regulation ON/OFF, minimum sensor reading, maximum sensor
reading
Parameter labels can be scanned in a circular motion by using the "up" (▲) key. To
exit the menu and return to normal operation, press the "down" (▼) key at any time
