Description The Type 99 gas regulators provide a broad capacity for controlled pressure ranges and capacities in a wide variety of distribution, industrial, and commercial applications. A Type 99 regulator has a Type 61L (low pressure), Type 61H (high pressure), or a Type 61HP (extra high pressure) pilot integrally mounted to the actuator casing as shown in Figure 1. The Type 99 regulator can handle up to 1000 psig (69,0 bar) inlet pressures (the 1000 psig (69,0 bar) regulator requires a Type 13

Improper use of this device in some applications may result in damage or injury. The user is urged to keep this book filed in a convenient location for future reference. These instructions may not cover all details or variations in equipment or cover every possible situation to be met in connection with installation, operation or maintenance. Should problems arise that are not covered sufficiently in the text, the purchaser is advised to contact Bristol for further information. EQUIPMENT APPLICA

A 1/4 inch NPT vent is provided on the pressure regulator body for this purpose. The vent location is shown in Figure 2-3. When air is used as the pressure source, the vent fitting may be allowed to bleed into the atmosphere. If fuel gas or other hazardous type gases are used as the pressure source for a Remote Set Regulator, the VENT port must be piped to a safe location. ** Warning ** Covers of Remote Set Regulators operating in hazardous areas should not be removed. If servicing is required,

The pushbutton switch is used to jump the load. 1. Adjust input test circuit for 4.995 V on DMM #1. 2. DMM #2 should read 20 mA. If necessary, adjust pot R50 to correct. 3. Press load pushbutton while observing DMM #2. If current reading increases, adjust R49 CCW. If reading decreases, turn it CW. Repeat procedure until change is less than ±.02 mA. 4. Final reading should be 20 mA, ±.02 mA. If necessary, reset pot R50 and repeat procedure. 5. Calibration is complete. Restore unit to normal opera

General The Bristol® 9110-RSR, from Emerson Process Management, is a bi-directional microprocessor based rotary actuator that sets the output of a pneumatic regulator. The output can be adjusted electrically by either discrete (raise/Lower) or analog inputs. These input signals to the “RSR” can be received from remote or local locations either by manual switches or automatic devices. Description Series 9110-00A, Remote Set Regulators are transducer devices that use an electrical input signal to
