1, the use of current alarm:
(1) Cut off the live wire of the monitored wire and cable and fix them to the monitoring terminals of the corresponding capacity of the current alarm. When monitoring the current greater than 5A, the AC current transformer (xA/5A) or DC current shunt (DC15 ~ 75mV) with corresponding ratio should be used.
(2) Connect the live wire of the power supply to the No. 1 terminal block of the current alarm, and connect the neutral wire to the No. 2 terminal block, and turn on the power.
(3) Set the monitoring current: Press the SET button once, use the right arrow key, the up arrow key ∧, and the down arrow key to enter the password 0089. Press the SET key to confirm. After the P-Sn option appears, press the SET key to confirm and enter the monitoring current. Codes 0-7, press the SET key to confirm. 0 represents DC-1 ~ 5A, 1 represents DC-0.2 ~ 1A, 2 represents DC-20 ~ 100mA, 3 represents DC 15-75mV, 4 represents AC0 ~ 5A, 5 represents AC0 ~ 1A, 6 represents AC0 ~ 10mA.
(4) Set the display range: Press the SET button once, use the right arrow key, up arrow key ∧, and down arrow key to enter the password 0036. Press the SET key to confirm. When the PvL option appears, enter the span zero value (0 for no current). ), press the SET key to confirm; then each press the up key ∧ or down key ∨, you can return to the previous option or enter the next option; when the PvH option appears, enter the full scale value of the value 5A, 1A, 100mA, 75mV (When using an AC transformer, enter the actual measurement value including the number of decimal places.) When the dot option is selected, enter the number of decimal places (0 to 3). When the Filt option is selected, enter the filter coefficient (0 to 3, the larger the value. The slower the reaction is displayed. When the End option appears, press SET to exit.
(5) Set the upper limit alarm value and the upper limit alarm reset value: Press SET key once, input password 0001, press SET key, when AH1 option appears, press SET key, input upper limit alarm value, press SET key to return to AH1 option . Press the up arrow key ∧. When the AL1 option appears, press the SET key to enter the reset value of the upper limit alarm value. The value should be lower than the upper limit alarm value. When AL1 = AH1, the upper alarm relay fails. When the End option appears, press SET to exit.
(6) When the upper limit alarm whistle, the J1 alarm lamp on the panel lights up, the normally closed terminal 18 and the common terminal 19 of the relay change from closed to open, and the common terminal 19 and the normally open terminal 20 change from closed to closed. When the upper limit alarm is reset, the whistle will be stopped, the J1 alarm light on the panel will be extinguished and the relay will be reset.
(7) Set the lower limit alarm value and lower limit alarm reset value: Press SET key once, input password 0001, press SET key, when AH2 option appears, press SET key, input lower limit alarm value, press SET key to return to AH2 option . Press the up arrow key ∧. When the AL2 option appears, press the SET key to enter the lower limit alarm value reset value. The value should be higher than the lower limit alarm value. When AL2=AH2, the lower limit alarm relay fails. When the End option appears, press SET to exit.
(8) When the lower limit alarm whistle, the J2 alarm lamp on the panel lights, the normally closed terminal 15 and the common terminal 16 of the relay change from closed to open, and the common terminal 16 and the normally open terminal 17 change from closed to closed. When the lower limit alarm is reset, the whistle stops, the J2 alarm light on the panel goes out, and the relay resets.
(9) Setting example: When using a 200A/5A AC transformer with a ratio of 40, P-Sn is set to 4, PvL is set to 0, PvH is set to 2000, dot is set to 1 (2000.0 for the smallest range, maximum range) Display 200.0), Filt is set to 1, the upper and lower limit alarm value and reset value can be set according to actual needs.
2. How to use the whistle strobe light:
Connect the black and white positive lead of the power adapter to the common terminal 19 of the high-alarm relay of the current alarm and the public terminal No. 16 of the low-limit alarm relay; connect the red positive lead of the strobe flash and the high- alarm relay of the current alarm No. 20 Normally open terminal, low limit alarm relay No. 17 normally open terminal is electrically connected; connect the black negative lead of the power adapter to the black negative lead of the whistle flash, and insert the power adapter into the power socket.
Low-iron glass, also ultra clear glass, is a type of high-clarity glass that is made from silica with very low amounts of iron. This low level of iron removes the greenish-blue tint that can be seen especially on larger and thicker sizes of glass. Low-iron glass is used for aquariums, display cases, some windows, and other applications where clarity is desired.
Tempered or toughened glass is a type of safety glass processed by controlled thermal to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
Tempered Glass ultra clear glass is a kind of safety glass, with low rate of explosion, high transmittance, to meet some request which need high transmittance. For some printed or back painted tempered glass, ultra clear glass as for subtract can provide the truest color.
