Class 8839 58M Enclosed AC Drives

Factory Engineered Modifications

Mod E218

Signal loss follower alarm relay

Provides one Form 'C' contact rated 5 A @ 120 Vac wired to terminal blocks for customer use. Intended for 4–20 mAdc control loop applications where upon the loss of input signal it is desired to retain the output signal at the last input signal level. The relay provides an alarm relay contact for signal loss alert.

Note: Requires use of logic output LO1.

Rules: Available on all configurations.

Mod E219

Inhibit/shutdown sequence (timed operation)

Provides a relay circuit operating in the fail safe mode where a remote initiating contact opens the relay, deenergizes, and after a specified time shuts the drive controller down in the AFC mode (hand or auto) and/or in the bypass mode (hand or auto).

Rules: Available on all configurations.

Mod E220

Check valve sequence (motorized type)

Provides relay circuitry sequenced from a check valve limit switch. A valve closed position limit switch will energize relays that will initiate a remote valve operating solenoid limited to 50 VA and give a run permissive to the drive controller in the AFC mode (hand or auto) and/or in the bypass mode (hand or auto). A valve closed position limit switch will de-energize a timer relay such that if this relay is not de-energized within a specified time period, the drive controller will shut down in the AFC mode (hand or auto) and/or in the bypass mode (hand or auto).

Rules: Available on all configurations.

Mod E221

Seal water solenoid - with pressure switch feedback

Provides a relay, which will energize a remote seal water solenoid limited to 50 VA during drive controller operation. Additionally, the remote initiating contact will open the relay, deenergize, and after a specified time shut the drive controller down in the AFC mode (hand or auto) and/or in the bypass mode (hand or auto).

Rules: Available on all configurations.

Mod E222

Moisture detection relay circuit (without relay)

Provides 24 V or 120 V control power to a customer-supplied moisture detection relay device, either electronic or electro-mechanical. Factory provides pre-wired socket or mounting space only.

Note: Customer supplies relay. Details concerning type must also be provided at time of order entry in the 'Engineering Notes' field within Q2C.

Rules: Available on all configurations.

Mod E223

Moisture detection relay circuit (with relay)

Provides 24 V or 120 V control power to a customer-supplied moisture detection relay device, either electronic or electro-mechanical. The customer-supplied moisture detection relay is mounted and wired by the factory.

Note: Details concerning type must be provided at time of order entry in the 'Engineering Notes' field within Q2C.

Rules: Available on all configurations.

Mod E224

Substitute Type K operators

Provides Class 9001 Type K 30 mm heavy duty multifunction operators in place of standard Telemecanique 22 mm pilot devices.

Rules: Available on all configurations.

Mod E225

Spare control relays

Provides unwired control relays mounted for customer use.

Rules: Available on all configurations.

Mod E226

Substitute pilot light lens color(s)

Provides the flexibility to configure lens cap colors to contract equipment designations.Note: specify lens cap colors desired at time of order entry in 'Engineering Notes' field within Q2C.

Rules: Available on all configurations.

Mod E227

Blown fuse indicators on control fuses

Provides blown circuit fuse indicators on control circuit fuses in lieu of standard fuses.

Rules: Available on all configurations.

Mod E228

Motor over temperature logic input

Provides dedicated terminals using an external motor over temperature input (N.C. contact) factory wired and programmed.

Rules: Available on all configurations.
