PoKo (potential free contact) Alarm plug connector

Signal contact for external monitoring

Observe the functional options, which the PoKo provides in the main menu.

The potential free contact (PoKo) signals the condition of the temperature control device by means of the contact position. A closed operating contact means ready status (must be set via the menu). The operating contact is open in case of a fault or error (this applies to the normally open contact between pin 1 and pin 2). Further applications are possible e.g checking of the actual value. The connection is designed as a potential free changeover contact.

Normally closed contact between pin 2 and pin 3.

Contact load: 1A at 24V DC

ECS Socket (External Control Signal) Standby

Release signal ECS (External Control Signal), for starting / stopping temperature control.

The ECS can be used to switch of the temperature control mode (internal/process), switch to the 2

nd

set-point or allow temperature control.

Control over a potential free contact. The contacts 1 and 3 are bridged internally. ECS becomes electronically active, if E1 and E2 are connected by an external zero potential free contact.

The functionality of the ECS is determined in the Com.G@te / Web.G@te menu under the point ECS Standby.

The following options are offered:

-

OFF: ECS does not have any effect (Factory default)

-

set-point: The 2

nd

set-point is taken over as soon as ECS is activated

-

Standby: ECS has effect on temperature control (ON / OFF)

RS232 / RS485 Serial Socket

A PC, PLC or a process control system (PCS) can be connected to this socket, in order to remotely control the controller. Alternatively, connecting to a RS485 bus is also possible (not valid for the Web.G@te). Before connecting the line, check and if necessary adjust the settings in the menu Digit. Interface.
