Control and safety stations (SUIZ) HMS Control L3 is intended for control and protection of deep-well electric pump units of ECV type, submersible pumps of Gnome type, their analogs both domestic, and import production, and also any three-phase asynchronous electric motors with a short-circuited rotor on commands of the operator or sensors signals and corresponds to requirements of TU 3432-112-00217975-2011.
The station provides functioning of the pumping unit in the following modes:
SUIZ corresponds to the climatic version U2 или UHL4 as per GOST 15150-69. (U2 - maintenance in not heated rooms or under a shelter at ambient air temperature from minus 40 up to plus 40°С and at relative humidity 100 % at 25 C, UHL4 - maintenance in the closed heated rooms at ambient air temperature from plus 1 up to plus 40°С and at relative humidity of 80 % at 25°С)
SUIZ protection degree from water and dust IP21 or IP 54 as per GOST 14254-96.
As protection against defeat by an electric current SUIZ corresponds to 1 class as per GOST12.2.007.0 -75.
Control and safety station consists of a board with the removable mounting panel in which circuit breaker, contactor starter, smooth start-up (UPP), electromagnetic relay, two terminal units (force and signal) and current sensors (current transformers) are installed. For versions 100... 300 shunting resistors for current sensors are installed additionally. There is a control and protection microcontroller "L3" on a door of a board (further MK).
Depending on execution, station can include the switch disconnector on supply input, module of temperature monitoring of windings of the motor and the module of protection against impulse overvoltage (lightning protection).
On MK front panel there are control buttons "START-UP", "STOP", «PROGR". « CHOICE», four-digit led indicator and light emitting diodes of sensors status, operation modes and emergencies.
On the back panel of MK case detachable terminal clamps for connection of external force electrical circuits and sensors are installed.
The principle of operation of SUIZ is based on the signal processing from external sources on MK, and operation of the smooth start-up which is switching on / disconnecting the electromotor.
Manual mode of operation is possible, at which start of the motor is carried out by clicking of the buttons "START-UP", "STOP", or one of automatic modes, at which start of the electric motor is carried out by signal from the sensor level or pressure.
The complete description of operation modes, setup and emergencies conditions is in Programming manual.
The description of smooth start-up operation is provided in the user manual UPP.
