Forest FAL-10G User manual

Heater broken alarm FAL-10G＜single phase,three phase dual use＞
■Characteristic
● Phase control,ON-OFF control,Zero cross control,etc can be used
regardless of the total
● One heater burnout detection in parallel heater
● Detection points can be set arbitararily by dual scale
● When the detection point is reached,"ALARM LP"lights,and an output
signal is emitted
● Three phase circuit is also OK with this one
● Panel mounting type(DIN rail only)
● RoHS compliant products

■Operating priciple
1. Direct line current of load by current detector (C.T) Heater broken alarm
convert it to voltage, and enter division circuit FAL-10G
2. The line voltage of the load is detected by the voltage detector(Tr2), ＤＩＮ rail mounting
and, it enters the division circuit through the current setting unit AC100V/200V ±10% 50/60Hz
and the alarm setting unit 0.3～5A(When exceeding 5A,C.T external attachment)
3. Divide circuit compares and divides both inputs, drives a relay 0～100V/0～200V
through a Schmitt circuit , and issues an alarm output 0.5KW for AC100V,1φ
Below direct connection
4. Since voltage and current are detected even if the power suplly changes ： 1KW for AC200V,1φ
(line current 5A or less)
both increase and decrease at the same rate. ： 1.7KW for AC200V,3φ
Due to this change no warning will be issued even if the current decrease. In case other than the avobe C.T use
Therefore this equipment can be applied even by using a power Linearity load such as Nichrome wire
supply device by thyristor phase control or the like. 3～100%
5. The malfunction prevention circuit operates when the load voltage ±1.5%(Full scale)
is 15% (15V when rated 100V,30V in the case of 200V) or less 0.5%(Full scale)
and the alarm output does not come out. Phase control, H-L control, Zero cross control

■Setting method ■Terminal connection diagram
1. Alarm set valueis gratuated with "%"
2. The setting "0 to 100" corresponds to the line current "0 to 5" of the load(heater)
3. Therefore,when the heater capacity is"AC100V 1φ 0.5KW, AC200V 1φ 1KW,
AC200V 3φ 1.7KW" the line current is "5A",so"0 to 100% directrly corresponds
to 0 to 5A"
4. If the heater capacity is smaller than 3. it becomes as follows.
For example,when the heater capacity is"AC200V 1φ 0.5KW", it bocomes "2.5A"
as a line current and corresponds to 50% of the setting scale.
※ If it is set to 51% or more, an alarm will be issued after terning on the power.
If you wont issue an alarm when "1/10" of all heaters are disconnected,
set it between "50 × 9/10 = 45% ∴ 45% to 50%"
”５０×９／１０＝４５％∴４５％～５０％”の間に設定します。
5. If the heater capacity larger than 3. it becomes as follow.
For example,if the heater capacity is "AC200V 3φ 10KW (delta connection)"
the line current will be "87A" and C.T will be used.
Considering the case of using "100/5A" C.T, the secondary side of C.T becomes
"4.3A" for the line current "87A", which corresponds to "87%" of the setting scale.
Therefore use "0 to 87%" setting.
※ If you set it to 88% or more, an alarm will be issued after turning on the power.
If you want to issue an alarm when 1/9 of all heaters are disconnected,
set it between "73 and 87%"
The table below shows the current change rate when one of the heater is disconnected
in case of multiple parallel connections under a balanced load.
Please refer to the alarm setting.
