Page 6: Introduction
1 Introduction Introduction The 340i / 680i/ 1220i DC Drive is an isolated, single-direction speed controller for brushed shunt wound or permanent magnet DC motors. This Class 1 product has basic insulation and a protective earth. Its control signals are isolated from the mains AC supply, and their connection to other isolated instruments is permitted. -
Page 7: Installation
2 Installation Installation 2.1 Motor installation • Foot-mounted motors must be level and secure. • Ensure accurate alignment of the motor shaft and couplings. • Do not hammer pulleys or couplings onto the motor shaft. • Protect the motor from ingress of foreign matter during installation. NOTE: This drive does not provide motor over-temperature protection. - Page 8 WARNING! When power is applied to the drive, ALWAYS use an insulated tool when adjusting the presets. USER ADJUSTMENTS Level: relay driver threshold. +/-(0.5% to 105%). (+/-10.5V). Symmetrical about zero. Level “Fan failure” alarm is active when lit. Alarm Refer to "3.2 Operating the drive" on page 13. Refer to text.

- Page 15 CONTROL TERMINAL LISTING - tightening torque: 0.25 Nm (2.2 lbf.in) RLIP Relay driver input. Accepts 0 to +/- 10.5 V signal inputs. The threshold to activate the relay driver is symmetrical around zero. This is set by the LEVEL preset, between +/-0.05 V and +/-10.5 V. When the T13 input exceeds the positive or negative threshold, then the T12 RELAY DRIVER OUTPUT is turned ON.
- Page 16 CONTROL TERMINAL LISTING - tightening torque: 0.25 Nm (2.2 lbf.in) TRIP This output goes high (+10.5 V at 10 mA) and latches high when the stall timer has timed out (in which case T14 OVLD will also be high), OR if the fan alarm has operated (in which case T14 OVLD will be low).

4 Options Options • Speed Feedback selection: If the system is to use Tacho feedback you can now adjust for the tachogenerator's output voltage, and hence the speed of the motor. Run the drive in Armature Voltage feedback mode and check the polarity of the tacho using a voltmeter. - Page 21 • Alarms WARNING! PERSONAL INJURY HAZARD The following alarm provides an electronic armature current inhibit function. The field output remains energised and all power terminals are LIVE (shock hazard), hence these terminals must not be relied upon to ensure the machine is stationary during hazardous operations.

TRIP OVLD RLIP RLOP Tach IP+/- OP+/- CAUTION! EQUIPMENT DAMAGE HAZARD Do not disconnect the supply while the drive is running. For drives supplied via an AC supply contactor, either open the T9 RUN input, or ensure that motor shaft is stationary and is not under load, before opening the contactor.
