Troubleshooting

WARNING: Do not open actuator cover while circuits are energized.

Q: What if there is no output, but the motor runs?

A:

Manual override possibly engaged.

When the manual override is engaged, the motor will run, but no output will be observed until the manual override re-engages with the output shaft.

A:

Valve stem broken. When the valve stem is broken, there will not be a change in fluid movement, making it seem as if the actuator has no output..

Q: What if valve does not cycle?

A:

No power source to actuator. Check for power.

A:

Power source disconnected. Check for broken wire, loose connection or no connection as per appropriate wiring diagram.

A:

Low or wrong power source. Check for proper voltage.

A:

Mechanical Brake jammed or misaligned. Check alignment of brake assembly.

This could occur during installation when someone would rest their hand on the

Mechanical Brake to steady themselves.

ASAHI/AMERICA, INC 35 GREEN STREET MALDEN, MA. 02148 TELEPHONE 800-343-3618

Q: What if there is water and/or moisture inside of the unit?

A:

Conduit fitting installed improperly. Re-install correctly.

A:

Cover and/or base seal damaged. Replace damaged seal(s).

A:

Base gasket damaged or installed improperly. Check gasket and replace if necessary.

A:

Temperature swings of more than 15 degrees F. Install heater and thermostat to eliminate condensation.

When these temperature swings occur, the unit will “sweat” on the inside causing internal corrosion unless the actuator is equipped with a heater and thermostat to keep a constant temperature inside of the housing.

A:

Unit has been submerged. Raise unit above liquid level.

An actuator that is to be submerged MUST meet NEMA 6 for the proper protection of the actuator and the elimination of a potential hazard. We do not recommend submerging the Series 92 Actuator as the electrical rating does not meet NEMA 6.

Q: What if unit is oscillating?

A:

Valve torque exceeds output torque of actuator. Check for chemical compatibility of valve, and flange torque.

Q: What if thermal overload frequently cuts out motor?

A:

Frequency of operation exceeds duty cycle rating. Check cycling period.

A:

Unit is oscillating. Refer to above.

Q: What if motor hums and no output is observed?

A:

Foreign material caught in valve. Remove material and inspect valve for damaged and/or worn parts. Replace parts as necessary.

A:

Unit wired incorrectly (simultaneously powering open and closed). Check wiring as per appropriate wiring diagram.

A:

Capacitor worn. Replace.

Q: What if actuator “over-shoots” limit switches without stopping?

A:

Actuator wired in parallel to each other. Please note that each actuator requires it’s own set of switch contacts.

Maintenance

Disconnect power!

WARNING: Do not open actuator cover while circuits are energized.

CAUTION:

It is imperative for reducing the chance of electrical shock, and to prevent ignition of hazardous atmospheres that you

Disconnect power

before

any maintenance or repairs are performed.

Series 92 actuators are virtually maintenance free. We do however, recommend that periodic checks are made to ensure that all fasteners are tight and properly torqued to extend the life of the actuator and valve.

Series 92 Actuators are manufactured with factory lubricated grease in the gear case and gearbox. In most cases, this lubricant should never have to be replenished, however if deemed necessary, we recommend using Aeroshell

Grease #33 MS, mfg. by Shell Oil Co.

Consult our technical department before replenishing lubricant.

For outdoor or wet locations keep top and bottom seals coated with a silicone based grease.

ATEX Requirements

ATEX Standard EEx d IIB Directive II 2 G Certified Units

Service/Maintenance/Inspection Requirements

Above directive for hazardous location service electric actuators, for use throughout the European Union.

All electric actuators are to be used for remote operation of a valve to open or closed positions. Any other uses are not approved by Asahi/America, Inc.

Every 250,000 cycles or 10 years whichever comes first, the actuator must be removed from service and sent back to Asahi/America, Inc. for inspection of wear of bearings as they relate to joints and gaps in accordance with above directive.

Any units not within normal tolerances, will need to be re-built or replaced at the users expense.
