NOTICE
The P159A Series Actuator is fitted 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
specified operating limits and the cutout continues to trip, replace actuator.
INSTALLATION
Check nameplate for correct catalog number and service. Check the catalog
number against Figure 1 to ensure that the actuator meets the requirements
of the application. Contact ASCO for more information about this actuator
or other actuator options if this actuator is not suitable for your application.
Positioning/Mounting
Follow the _158A or V710_B Series Gas Valves and/or damper
manufacturer’s instructions when installing the actuator.
1. The P159A Series Actuator can be installed to operate in any position.

Opening Time:
Fast Opening:
•
Typical t
ime approximately 9 seconds
•
At temperatures below -30 °C, actuator may take as long as 30 seconds
Slow Opening:
•
Typical time approximately 18 seconds
•
At temperatures below -30 °C, actuator may take as long as 60 seconds
Maximum Closing Time:
One second
Ambient Temperature and Duty Cycle Limitations
T
he actuator may be operated in ambient temperature conditions from -40
°C to 66 °C (-40 °F to 150 °F). During normal operation, the P159A series
Actuator can be cycled CLOSED to OPEN, up to 4 times per hour at maximum
ambient temperature of 66 °C (150 °F). Higher cycle rates are possible with
lower ambient temperatures. During commissioning at room temperature
of 20 °C (68 °F), the actuator can be cycled up to 60 times per hour.
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 t
o 9,0 ± 0,5 N-m (80 ± 5 in-lbs)
using a 4 mm hex bit socket. Ensure actuator base is fully secured against
valve body mounting surface for proper operation. (See Figure 2).
Wiring:
(Refer to Figure 3 for On/Off Actuator & Figure 4 for High/Low/
Off Actuator)
WARNING
Electrical hazard. To prevent the possibility
of death, serious injury or property damage, open all
circuits before inspection, service or disassembly.
AVERTISSEMENT
Danger électrique. Afin de prévenir
le risque de décès, de graves blessures ou de dommage
matériel, ouvrir tous les circuits avant l’inspection, la
maintenance ou le démontage.
