Supply voltage range must be determined in order. While installing the unit, supply voltage range must be controlled and appropriate supply voltage must be applied to the unit. Controlling prevents damages in unit and system and possible accidents as a result of incorrect supply voltage.

There is no power switch or fuse on the device. So a power switch and a fuse must be added to the supply voltage input. Power switch and fuse must be put to a place where user can reach easily.

Power switch must be two poled for seperating phase and neutral. On/Off condition of power switch is very important in electrical connection. On/Off condition of power switch must be signed for preventing the wrong connection.

External fuse must be on phase connection in Vsupply input.

4.2.3 Adjustment of Hysteresis Value for ON/OFF Control

In ON/OFF control algorithm, temperature value is tried to keep equal to set value by opening or closing completely last control element. ON/OFF controlled system, temperature value oscillates continuously. Temperature value’s oscillation period or amplitude around set value changes according to controlled system. For reducing oscillation period of temperature value, a threshold zone is formed below or around set value and this zone is named hysteresis.

Relay Output : Output period must be short

for stable process control. Relay must not be used in short output periods because of limited life of their relay contact (number of open/close events). SSR Output : If short output period is needed in a system (approximately 1-2 seconds) SSR driver output module as last control element is recommended.

Example : For a (0 , 400°C) scaled device, proportional band is adjusted 15 with proportional

band adjustment and ON/OFF control form trimpot, control period is adjusted 10 seconds with DIP switch. The system will give 100% output, until temperature is in proportional band, namely until temperature is 340°C (Scale*15/100 = 400*15/100 = 60). When temperature is being close to set value, %output is started to be reduced. In this case, when the device calculates 60% output, the system will be energised for 60% of device’s control period. (For this example; 60% of

10 seconds Þ 6 seconds the system will be energised, but the system will not be energised for 4 seconds)

4.2.5 Adjustment of Set Offset Value

Set offset value can be adjusted with set offset trimpot that is located on front panel.

When temperature is not equal to SET value, to remove the difference between SET value and temperature and to make equal the temperature and SET value, Set offset is used. It can be adjusted from -20% to 20% of full scale. Minimum and maximum value of Set offset value according to the type and scale of the device are given below:

Set offset Values according to the type and scale of the device

For PT-100 ( -100.0 to 100.0 )°C scaled devices : (-20.0 to +20.0)°C For PT-100 ( 0.0 to 200.0 )°C scaled devices : (-20.0 to +20.0)°C For PT-100 ( 0 to 400 )°C scaled devices : (-8 to 8)°C For J Type TC ( 0 to 400 )°C scaled devices : (-8 to 8)°C
