1. Getting started guide: GS24S/xx-360 with 9-pole screw terminal block 1. Select operating mode on J1 (the default internal mode is Standard, which is obtained by setting J1 on I). Select J2 (Standard is internal RF). 2. Connect the following digital input (Connect terminal 7 to terminal 9; Input for enabling the regulator when J2 is set on External). 3.
2. General information / Operation The series GS 24 S/xx-360 transistor speed controllers are inexpensive devices with compact dimensions of 72 x 100 mm for the stepless speed control of any DC motors at low voltages and motor currents of up to 10 A. The input voltage range is 20 to 36 V DC makes a battery operation possible, e.g. from an on-board electrical supply system or through series SNT 24/xx mains adapters connected upstream.
3. 2.2. Accessories ● Module carrier for 35 mm mounting rail installation. ● Module carrier for screw fastening. ● Suppressor diodes in motor vehicle applications with high inductive spikes. ● Potentiometer for set point adjustment 1 gang or 10 gang (10kOhm). ● Mains adapter SNT 24/ 05; NT 24/ 10 input voltage 230 V / 50 Hz.
In Germany the VDE regulations and the regulations of the Health and Safety Executive apply. In addition, the regulations set forth by the EMC and Low Voltage Directive need to be complied with as well. Machines and equipment are also required to include device independent monitoring and safety provisions. The user must ensure that in the event of a device malfunction, foreign operation, outage of the control and regulation units, etc., the drive is brought to a safe operating condition.
3.2. Installation, start-up and safety measures ESD-protection / Installation instructions Attention during installation of the electronic board! It must be warranted on your part that there is sufficient ESD-protection. An external mains adapter is required for the electrical supply of the controller EPH 360. If this mains adapter is itself supplied with a voltage >75V AC or >50 V DC the following points need to be considered: The unit should only be installed by qualified specialist personnel.
3.3. EMC measures Make sure that the controllers are suitable for operating in the required EMC environment. EPH Elektronik supplies special mains filters and enclosures that are designed for the specific controller and which are able to provide not only the best possible protection against interference, but also the best damping, low noise emissions, simple mounting and installation, as well as the necessary electrical safety.
3.4. Low Voltage Directive 73/23 EWG “Electrical equipment must not jeopardize the safety of people, domestic animals or property if operated at a voltage range between 50 V and 1000 V alternating current or at a voltage range between 75 V and 1500 V direct current.” EPH Elektronik supplies racks with IP 20 security rating to provide protection against direct contact in accordance with the Low Voltage Directive 73/23 EWG, which also applies for the mounting of the mounting plate.

4.1. Option change of rotating direction -Type: 393 General information / Operation The additional circuit board 393 provides the facility to change the rotating direction of a permanent magnet motor with a transistor chopper controller type GS 24 S/xx-360 under low voltage of 12 to 48V DV and a nominal current of max. 6A (10A*) Rotation in the left or right direction can be pre-selected during standstill via a 12 V to 48 V DC control signal.
