4. Description of external keyboard
To use external keyboard SOP-20-810 for debugging, CV800dedicated HEX configurationfile must be
configured. SOP-20-810 should have built-in matched resistor and pull-up resistor.
CAN communication is used for keyboard communication, and it is within the same network of the CAN
of air conditioning control panel. When 23PIN aviation plug is connected to 24V, the keyboard may
search CV800-DCDC equipment, and connected to 24V and 540VDC, CV800-INV equipment may be
searched. When disconnect 540VDC, CV800-INV will display communication drop. To have
CV800-INV (keyboard scans the equipment once after power-on and the first scanning time may be
1-2min) displayed after power-on again, reinsert he keyboard. Communication of SOP-20-810 LCD
keyboard is carried out with dedicated communication protocol and three devices in CV800. For details
of LCD keyboard upgrade and file configuration, see Appendix A.

●Ordinary digital control keyboard is not supported in CV800 products.
● Driver RJ45 and aviation plug shares the same CAN network, which can be connected to the
keyboard by means of aviation plug switching cable.
If the air conditioning panel used is fitted with built-in resistor, when tested in factory, before inserting
SOP-20-810 keyboard for debugging, toggle the CAN matched resistance of PLC to position “OFF”,
otherwise, communications might be unstable. If SOP-20-810 keyboard is not used, when the air
conditioning is delivered, be sure that PLC is in the position “ON”(i.e., 120Ωmatched resistance is
located at both ends of air conditioning CAN communication network).

Description of special load usage:
◆Contact protection when inductive load is used
When inductive load is used in the product, it will produce very large back electromotive force between
contacts between when it ceases as well as arc discharge, which may cause the contact failure of
contacts or contact sinking, significantly shortening the service life of contacts. It is recommended to
use products with built-in protection loop. If load without internal protection loop is used, use external
shock protection circuit to reduce noise and prolong the life of the product.
Relay DC loop (Y00/Y01/Y02/COM1)
Connect fly-wheel diodes in parallel on load. Diodes need to meet the following requirements:
①Reverse voltage: 5~10 times of load voltage; ②Forward current: greater than load current.
Inductive load
Fly-wheel diode
◆Contact protection for using capactive load
When using capacitive load, if electric shock occurs, surge current 20 to times greater than the
conventional current may flow through the circuit. Note that the surge current cannot exceed the
current value at the maximum load of the resistance load.
In addition, capacitors and other capacitive loads may be present under the load of electronic circuits
such as inverters.
