Hydraulic Oil Level and Temperature Switch (HOLTS) meets requirements in ASME A17.1-2010/CSA B44-10 220.127.116.11 and 18.104.22.168 in one convenient tool.
? Monitors the temperature and level of the oil in the pump tank per ANSI 17.1 22.214.171.124 & 126.96.36.199
? Temperature switch is rated to trip at 149 degrees F (65 Degrees C) for use with Grade 32 Hydraulic Oil. (Other tripping temperature switches are available upon request)
? Mounts to any manufacturer's new or existing oil tank.
? Mounting bracket can be used as a drill fixture for mounting to the oil tank.
? (4) Holes are required for mounting (2) ?? (1) 9/16? and (1) 7/8?
? Threaded rod is fully adjustable to ensure float switch is at the appropriate height in any tank.
? Combination Float and Temperature Monitoring Switch
o (1) Normally Closed Temperature Contact
o (1) Normally Closed Float Contact.
o Max Rating 120VAC 2.6 Amps
The Hydraulic Oil Level and Temperature Switch (HOLTS) can be retrofitted to any manufacturers hydraulic oil tank. After field drilling (4) holes with our fixture and mounting (2) bolts, the threaded rod can be adjusted to the appropriate height to allow the float switch to trip when the oil level falls below the appropriate level by code. If the oil level falls below the minimum allowable level by code, or if the temperature rises higher than the maximum allowable by code the switch will be activated sending a signal to the controller to stop normal elevator operation.
Please note that Vator Accessories is providing the temperature and level switch and mounting only! The switch will need to be wired to the controller. The controller will require the logic to follow the recommended operation below
1. The Hydraulic Oil Level and Temperature Switch (HOLTS) is tripped when the oil level or temperature in the hydraulic tank fall below code allowable level or above code allowable temperatures.
2. The Hydraulic Oil Level and Temperature Switch (HOLTS) normally closed contact open if either oil level drops or if temperature becomes too high.
3. The controller receives the open contact signal from the (HOLTS) switch.
4. When the elevator doors are closed, the car shall automatically be brought to the lowest landing and prevented from normal operation until it is reset by a qualified Elevator Mechanic or Elevator Inspector.
