Opening Time: Fast Opening: 14 seconds max.
Slow Opening: 26 seconds max.
Note:
Opening time doubles below -30°F (-34°C).
50Hz operation increases opening time by 20%.
Opening time is not fi eld adjustable.
Maximum Closing Time: One second
Ambient Temperature and Duty Cycle Limitation
s
The actuator may be operated in ambient temperature conditions from
-40°F to 150°F (-40°C to 65°C). Actuator can be cycled open / close
continuously below 108°F (42°C) for 60Hz and below 90°F (32°C) for
50 Hz. See chart below for limitations (open / close cycles) at elevated
temperatures.
NOTICE
The AH4E actuator is fi tted with a self-resetting thermal cutout device. If
the recommended temperatures and duty cycles above are exceeded, the
thermal cutout may trip causing the actuator to stop in its current position
during valve opening. The valve closing time remains one second or
less regardless of thermal cutout trip. Once the actuator cools,the cutout
will self-reset and the actuator will resume operation. If the cutout trips
repeatedly, verify that the application is within the ambient temperature
and the duty cycle limits of the actuator. If the application is within the
specifi ed operating limits and the cutout continues to trip, replace actuator.
INSTALLATION
Positioning/Mounting
Follow the V710 Series Gas valve and/or damper manufacturers
instructions when installing the Hydramotor .
1. AH4E actuators can be installed to operate in any position.
2. Check to ensure that the mounting gasket, if applicable, is in the
proper position, clean and without damage. Position the actuator to
operate the valve (and damper if appropriate). Secure actuator with
the three mounting set screws. Tighten set screws to 80 ± 5 in-lbs [9,0
± 0,5 Nm] using a 5/32 hex key wrench. (See Figure 1)
Wiring (Refer to Figure 2)
WARNING: Electrical hazard. To prevent the possibility
of death, serious injury or property damage, open all circuits
before inspection, service or disassembly.
Wiring must comply with local codes and the National Electrical Code.
Limit controls must conform with actuator rating (voltage, amperage,
hertz). Wiring to meet NEC Class I, suitable for 90 C. Wire limit controls
to the hot side of power supply.
1. Check the nameplate and confi rm that the appropriate power is
being supplied to the unit. Remove the front cover (with nameplate)
and set aside to access electrical connections taking care not to
damage the cover gasket if supplied. A diagram is located on the
inside of the cover to aid in making electrical connections.
2. Remove the desired electrical knock out and install appropriate
electrical ttings. Type 4 ttings must be used with watertight
units. Route wiring through the tting. Take care not to scratch
or otherwise damage the cover sealing surface when working on
watertight enclosure.
3. Connect the power to terminals 1 and 2. The neutral wire, if
applicable, should be connected to terminal 1. Connect the ground
wire to the grounding screw provided on the housing next to the
terminal strip.
4. Torque terminal screws: 8 to 12 in-lbs [0.9 to 1.3 Nm].
Torque ground screw: 20 to 25 in-lbs (2.3 to 2.8 Nm)
5. Connect wiring from an external high- re switch (not supplied)
to the 2-way terminal block. The switch must be rated at 240V
minimum and 2.5A minimum. Torque terminal screws to 8 to 12
in-lbs [0.9 to 1.3 Nm].
