Table 12 System Connectivity
HART Physical Device Type
Actuator; HART device type 7
DD Registered with HART Communication
Foundation
Yes, available through HART Communication Foundation
AMS Driver for Fisher-Rosemount Asset
Management Solution
ValVue 2 AMS SNAP-ON application available
Diagnostics
Options include: Valve signature, positioner signature, extended actuator signa-
ture, friction, stroking speed, step response, cumulative travel, cumulative cycles,
and time of operation in near-closed position. Some diagnostics require pressure
sensor and ValVue 2 software.
Table 13 Pneumatics Single Acting Standard Flow
Air Supply
Dry, oil-free, 5 micron filtered air (See ISA S7.3)
Action
Direct
Supply Pressure
20-100 psi max. (1.4 to 7 Bar)
Regulate 5 to 10 psi above actuator spring range. Do not exceed
actuator rating.
Air Delivery - Single Acting Relay
10.0 scfm (280 l/m) at 30 psi (2.1 bar) supply
16.6 scfm (470 l/m) at 60 psi (4.2 bar) supply
23.3 scfm (660 l/m) at 90 psi (6.3 bar) supply
Air Consumption
0.2 scfm (5.7 sl/m) at 30 psi (2.1 bar) supply
0.26 scfm (7.4 sl/m) at 45 psi (3.1bar) supply
Air Supply Failure
Single Acting Relay
On supply failure the actuator output drops. Some overshoot may
occur when air pressure returns after a period without air supply
pressure. Always set control set point to 0%, and put the process
control system in manual, for smooth recovery from air supply fail-
ure.
Loss of Input Signal
Output drops to low pressure.
Output Pressure
100 psi (7 bar) max
